We got the best comment this weekend.
On a steep climb at the very end of a two day trip we (50+) passed a teenager walking his mountain bike up the side of the road. His comment?
"Woah! You guys on your way home from the Olympics? I hope I can ride like that when I am as old as you. Can't even do it now!"
That was just what the stoker and I needed to get out of the saddle and power over the top.
