Burro Schmidt Tunnel ?

There is a tunnel between the entertainer compound and also a compound consisting of three homes built by a shell company of the company that is a huge part of the music festival.

@fogdryer @darkknight111 do we know which compound this blind is referring to?

Goldenvoice, subsidiary of AEG..

Gary Tovar is known as a music promoter and marijuana smuggler in the US. He named his music concert business Goldenvoice Productions, after a strain of marijuana that users said gave them a feeling of being spoken to by angels. Tovar is no longer involved with smuggling but acts as a consultant to Goldenvoice, which now operates the Coachella Valley Music and Arts Festival ..

Tovar was born in Los Angeles[2] and began smuggling illicit goods as a 14-year-old when he brought fireworks into the US from Tijuana in Mexico. Influenced by someone referred to as LaRue, who was connected to Timothy Leary's The Brotherhood of Eternal Love, Tovar's involvement with marijuana began in the late 1960s, with his sources for the seeds that he distributed including US servicemen on furlough from the Vietnam War. His organization was such that he was able to guarantee a market and a distribution network for the growers to whom he sold the seeds. The strains that he imported included Thai stick and Acapulco Gold.[1] He earned many millions of dollars before being arrested by federal drug agents on March 9, 1991. He fought conspiracy charges from Los Angeles County Jail before being imprisoned in October 1992 for seven years on four counts relating to trafficking from Arizona.

..The Olympic Auditorium shows ended in 1985 as interest waned but Goldenvoice moved successfully into other venues such as the John Anson Ford Theater, where tickets for concert by The Ramones were sold for US$5.[2] The business promoted some of the first concerts by bands such as Nirvana and Red Hot Chili Peppers,[4] expanding beyond punk to be in the vanguard of the speed metal, Goth and alternative music movements. In 1986,[5] he had met and employed Paul Tollett, an upcoming ska promoter; a year earlier,[6] he had employed Rick Van Santen, who managed 45 Grave. Tovar pulled out of the music venture in 1991 and has cited the losses and the increased levels of violence as his rationale. There had been, for example, three major riots at promotions in 1983. Now facing the trafficking charges, Tovar signed the business over to Tollett and Van Santen free of charge. Goldenvoice launched the Coachella festival in 1999. Tollett and Tovar remain friends, and Tovar attends Coachella every year as well as operating the "Tovar and Otis" hand made merch tent with his long time artist and merch partner Bad Otis Link. Tovar also remains a consultant to the company; Van Santen died in 2003.

Tovar now has a medical marijuana card. He is sometimes called an Anglophile and is no longer involved in illegal activities, describing his current interests as "English fun".

World War II's command headquarters for General George S. Patton's huge Desert Training Center, established for the training of troops in desert warfare, was established sometime in 1942. It was located not far south of Indio, Riverside County, near the present junction of U.S. 10 and State Route195, where the Cottonwood Springs Road runs up through the Joshua Tree National Monument.

In early March of 1942 the War Department ordered Major General George Smith Patton, Jr., U.S. Army, to locate, create, equip, and command a desert training center in California to prepare troops to fight the Nazis in North Africa. These Army Ground Forces and Army Air Forces were to become skilled in desert warfare.

The area chosen in the Mojave Desert was ultimately 350 miles wide and 250 miles deep. On 20 June 1942 the War Department acquired the land from the Department of the Interior by Public Land Order No. 1. The area included several sections in Riverside County, ranging from Indio, California to Arizona and from Las Vegas to Yuma. On May 12, 1942, by announcement of General Orders No. 7, the Desert Training Center was named Camp Young. On January 27, 1943, by announcement of General Orders No. 8, Camp Young "proper" (3,279.89 acres) became the Headquarters of the Desert Training Center/California-Arizona Maneuver Area (DTC/CAMA). By November 1943 CAM had enlarged and included Camp Young, Camp Coxcomb, Camp Iron Mountain, Camp Granite, Camp Essex (later renamed Camp Clipper), Camp Ibis, Camp Hyder, Camp Horn, Camp Laguna, Camp Pilot Knob, Camp Bouse and several bombing and artillery ranges.

..Between 800,000 and 1,000,000 soldiers prepared for warfare at the CAM. Camp Young was the administrative headquarters and the focal point of the maneuvers area for General Patton's 3rd Armored Division. The overwhelming focus of the training was on tank warfare. Camp Young remained the focal point for the CAM until the closure of the center in 1944. In January 1943 per General Order No. 9, First Headquarters Special Troops was organized to supervise training and administer non-divisional units, except Field-Artillery, in the desert. Due to the large area of the CAM, three additional Special Troops Headquarters were created to control and supervise. The 601st Engineer Camouflage Battalion was assigned to Camp Young December 1942. Also, stationed at Camp Young was the IV Corps Command Headquarters. From October 1943 to January 1944 the primary mission of the headquarters transitioned from purely training activities to almost 100% Preparation and Movement of units for Overseas Shipment.

A series of 13 ranges was constructed south and west of Camp Young. The ranges were designed for small caliber arms and for mortar fire including 37mm, 75mm, and 155mm. Shaver's Summit Army Air Field (a small runway) was built east of and adjacent to Camp Young.

Almost all the land acquired for the California - Arizona Maneuver Area was declared surplus by the War Department on 16 March 1944. The land acquired for the Camp Young site was relinquished on 14 January 1947 to the Department of the Interior by Public Land Order No. 342. The Camp Young site consists of 3,279.89 acres.

Seems like everything leads back to Epstein, one way or another.
