Glad to help. Don't let the confusing road network get you down. One of the "nice" things is that Pittsburgh is still a rather small, compact city. Become familiar with the area, then even when you get "lost" you just keep going and you'll soon "pop out" into an area that you'll recognize. It's kinda cool in a way, once you get used to it.
My running route is to go up Negley street at 5th avenue and then "get lost in Squirrel Hill".
Sounds like you're living in Shadyside, somewhere near "Nut" Street. Not a bad route to go jogging! (especially considering where you'd wind up going in most other directions -- although Highland Park is kinda nice at the other end of Negley.) (BTW, that's Negley "Avenue", not "Street")
