You'll find plenty of nice rides in that area. I actually lived in the south hills (Baldwin Borough) of Pittsburgh for most of my life. Now I'm just an hour further south, so I still ride there a lot. My club
The Western Pennsylvania Wheelmen have regular scheduled rides in that area as well. They also publish a map book, or CD with routes all over our area. It's a good group of people, and they have rides for every type, and ability of rider.
Hope to see you on the "Burgh" roads soon,
