This picture tells a lot, notice the flag on the cranes on the overpass (you can bet they had no permit for that) Also notice all the people on the overpass and standing on the right side of the road. There are cars stopped on the opposite side at the ramp as well. Many police and troopers helped block traffic for the riders even though they had no permit.
This is a stark contrast to the 25 or so the MMM. You can also bet this scene was played out many time around the city yesterday.
One quote I read was classic it said it was fitting that the Muslims were surrounded by hundreds of thousands of Hogs (Hog being a slang for Harley Davidson Motorcycles)
