I guess I just take it for granted, living in Oregon/Portland... I've never had anyone road rage at me. The worst I get is truckers blasting their horns at me when I ride a particular industrial artery in NW Portland (Yeon), but they're just being *******- it's 4 lanes and the shoulder is huge.
A lot of you guys live in some bike un-friendly places where it probably sucks to ride. Feel for ya!
