If you're genuine, I can't thank you enough for your interest and bravery to face this issue. I have a life away from all this, yet I don't really have my mind all together lately when I'm thinking of this BS; in some way, I wish for nothing else but to be in your position, making moves and feeling productive.

If you happen to be in the area, one thing we'd like checked out is the Trolley Turnaround Park located at: 1101 Monroe St NW, Washington, DC 20010. As others have said, it would be better organized if you could use your authority to inspect places that the layman could not. Don't do anything too extreme or conspicuous, don't be a nuisance, but if you happen to see anything from street view that you think would be worth capturing, please share. No need to go all out at once here.

And finally, if you're unsure about your safety or privacy submitting information under your pseudonym, you could PM a mod or reputable member here with attachments and so on.
