Wow. What a Fantastic experience. The trails are flat, wide, and have fantastic views along the way. Took my wife, 5 year old, and two year old. My five year old biked himself and we pulled my two year old along with the tag along bike.
You get to bike all over Pittsburgh, go across bridges, all without being in traffic. For renting two bikes, and biking 2.5 hours it came to $53. Not so bad. I can't wait to do it again!!
