As I was pedaling up a decent little hill and huffing and puffing a little bit 3 young college kids came up on those electric rentals and I hear the boy say put your motor on to make it up the hill. Of course they all passed me but, about a mile on up, there they were taking a break as my bride and I rode past them. Just made me smile that 60 year olds were really in better shape ( in a way) than they were.
