March Estimates: Police concur that the best estimate on the size of the March will be somewhere in the hundreds, not thousands, of participants.
Counter-Protest Estimates: Police estimate that there could be as many as three thousand (3000) bikers trying to circle the March and drown out the sound of the speakers at the kick-off rally with their engine noise.
