Sorry you had a rough day man. I can't help being uncomfortable with that stuff even after i've talked to them, or emailed several times. The ones I've done haven't been as likely to turn into wild goose chases, but I'm still left to wonder if it's a hoax, and if it'll be worth the trip(trips here can be quite lengthy too). So far they've all mostly paid off, and at least i've never came up completely empty.
