girllrig, I had a friend like that as well. Unfortunately, she is no longer with us. At least she didn't ask people for money this way. I think there's a difference between hitchhiking (which, ultimately, doesn't cost the driver extra assuming they don't go out of their way, and they might want the company) and asking strangers to fund your travels. I don't choose to do either, but I think there's a difference.
Liz, I didn't see any other selling point. I bet they have a website. I'll look for it.
