Did a 52 mile out and back on this trail and it was wonderful. Sorry no pix yet, just take my word for it if you are in earshot of this trail, do it. Wish we had more time to ride the length. Although I did not rub it in it is comforting to know you are in way better riding shape than your kid!

The amazing thing is it is all paved! 72 miles.
