ah, so *that's* why there were almost no campsites left. I'm headed there with family, but driving (first camping trip with the dog). Thanks for the heads up on the crowd, and have a lovely ride & weekend
oh, Steelvalley trail official opening is at 10:30AM or so on the 17th, look at the thread http://bike-pgh.org/bbpress/topic/steel-valley-trail-1 . Should be able to park at Waterfront for the whole trip.
