Video From DNC Critical Mass
with this information from: DVONS27
"Critical Mass in Denver during the Democratic National Convention. It was awesome. Probably at least 600 riders. At first the cops were escorting us, and were allowing us to go through red lights, but at the end, they said we were impeding traffic, so they sent out the riot police. People started getting arrested, and getting tickets. More Bikes, Less Oil! "
