You have to get out of the the city a little bit. The last hitchhiker I picked up was on Rt 422 north of Pittsburgh. It was cold, dark and raining so I stopped to pick him up. We got to talking and he told me his story on why he was hitching. Seems his buddy was having a bachelor party and he wanted to go. His wife hid the keys and said he couldn't go so he hitchhiked to the party and back. I dropped him off at his house and I can only imagine the hell he got from his wife when he got home...
I've dropped some off on the onramp of the Parkway before. We don't get many, but every once in a while.
