I'm hoping to get to Trexeltown on my annual summer trip to the Pittsburgh inlaws. I've also been meaning to try the the old track on Londonderry NH . It looks like fun.
OT; To get out of traffic I ride an old unpaved rail bed on a fixed psychocross bike. Its 18 miles one way with very few road crossings and ATV's are baned. Its great for grinding out some miles without worrying traffic. Just me and my bike.
