There's a great trail website, and also a growing Yahoo Group.
This will be a great thing. It'll open up a lot of small communities to tourism, it'll make the overall network more valuable (there's a cross-Ohio trail under development that'll end near Erie), and it'll make Pittsburgh bicycling more visible.
EDIT 12/06: This trail also connects to the Presque Isle network, including a 13.5 mile bike trail which is a National Recreational Trail.
Speaking of which (Pittsburgh bicycling), the Pittsburgh Dirty Dozen was held this morning, looks like they had nice weather for it. Photos will appear here.
