Well here's a guy that travels to Algiers and really gets about Washington DC and NYC. Was at the Grand Lodge, F.A.A.M., Washington, DC a week ago ... and he sure has DC mapped out. Pharmacies, pizza places, vets, schools, numerous different churches, drycleaners, ob/gyn's. hospitals, orphanage addresses, the 'Exorcist Steps', The Residence of the German Ambassador, John Hopkins, daycares, Embassies of Romania, Burkina Faso, Kyrgyzstan, Madagascar, Malawi, Cote D'Ivoire, Chad, Myanmar, Columbia, Embassy of Tribal Nations, US Postal Service, Places on Dupont and then there's NYC.
