I love riding my bike on these greenways. A paved path is so nice to ride your bike on. (Well, paved most of the way.) And 12 miles of uninterrupted path (6 each way) is a great workout. The scenery is beautiful and the atmosphere is so peaceful. I usually don't hear any sounds of traffic except when passing by (or under) highways/roads.
The downside is that it's often too popular. I certainly don't mind sharing the greenway with other folks, but I wish they felt the same. There are a lot of rude people out there who feel it's their right and privilege to walk spreadout across the path, creating a wall and barrier, not letting joggers and bikers pass easily. Seriously, move the eff over. Do you drive down the middle of the road, too? I didn't see your name on the greenway sign, so I'm guessing you don't own the path.
