It is illegal now to ride on any part of the CB parkway. There aren't any signs posted, but there's a code article somewhere... Not to say I haven't followed a few group rides on the parkway myself....

A friend of mine was out at Hains today during the noon ride and said that a truck that was following and filming the group nearly took him out. There were only a couple DC Velo guys out there today.

I have seen filming going on at the corner of Piney Meetinghouse and Glen (Glen Mill? South Glen? I forget where the name change is) up in Potomac nearly every weekend for a while. The guy had a big sign that said "Dangerous cyclist behavior" or something like that. Weird. I guess rolling through a 4-way stop at 5mph when it'd be your turn anyway is a dangerous thing. It's kind of like the cops at Hains that require you to put a foot down. I think there's no need for me to get off my bike so long as I can safely let cars go in order at all-way stops.
