I'm at a parking ticket vending machine on the south side of Vine Street. You'll need to go north for a stretch and you'll pass Ten Penn Center and Arch Street Presbyterian Church and a cathedral and Vine is a split road and I'm on the part that's on the north side of the highway so ignore the first Vine street and to the further one north and then go a half block west and that's where I am at. There is a library a half a block west of me which means you've gone too far if you see that.
