Earlier this year, the Washington Post had an article about the hazards of local MUCs and the blame seemed to be pointed at the cyclists. About a month ago, there was a letter to the editor on the same topic. The writer claimed that cyclists were going 30mph on the Mt. Vernon Trail (hmmm, I'm not sure that's possible, given the trail's windy nature, bumps, etc.).

While I've encountered cyclists going way too fast for conditions, taking corners incorrectly at higher speeds, and engaging in unsafe behavior, most of the "hazards" I've encountered have been on foot (IPOD wearers), moms w/stollers, or inexperienced cyclists (wobblers, IPOD wearers, kids, et.al.). Julie is right that there are a lot of angry people in this area who take their anger out on others---cyclists are a popular target.
