Last week I was in my car (had my golf clubs with me, or I'd be on the bike) and passed a mom biking down a hill, going the wrong way. Down a steep hill, at a fairly high rate of speed. Oddly enough, her kids, which were about 10 years old, were ahead of her going down the hill in the right lane. She appeared to be yelling at them to switch lanes.
Funny thing is that I don't even ride this section of road on my bike--in fact I won't take my car on it when it's icy since it's that steep. It's dangerous. It's very busy, the road winds down the hill, and it's narrow. More importantly, there's a very nice bike path parallel to it a half mile away.
