ps. One time we saw this woman who was flying down a super steep hill with a stop at the bottom and a super busy road at the stop. She didn't have time to stop quickly and unclip and really wiped out - she was in bad shape. We had to call an ambulance. That is really scary. When I go down super steep hills I still use my breaks (I know I shouldn't) - but how in the world do you handle a hill like that? Unclip as you're going down in case there is a stop at the bottom?
