Thumbs up for Wacky! Way to go, and good job keeping at it on the hilly parts.

About the scary driver thing: Yes, there are jerks out there who'll gun for you and make your life miserable. But I think it's important for us not to be intimidated by those drivers -- and also not to overreact (as in the Critical Mass fiasco in Seattle). Shame them with your good grace and your uncowed riding; wave and smile at people who honk at you. Keep riding safely and legally. It's the classic "love those who hate you" scheme, and the bonus is that being legal and nice in response to car nastiness is like lemon juice on that irate driver's already raw road rage.
