I'm with you Mike. Any of those stupid fans that get too close should be tazed, but the trouble is, you can't clear the people out of the way fast enough with security, but maybe you could do something if you had 2 motorcycles riding side by side to clear them out initially, but they would just flow back into the road.
Last year, one of the riders actually hit a fan with his hand who got too close. Maybe part of the standard gear that the riders could have is electric cattle prods to get rid of the idiot fans.
And yeah................those riders are TOUGH. I used to ride a bicycle everywhere I went during the last 10 years in the Navy, and even though I did 50 to 100 miles/day for over 10 years, I was never anything close to what those guys are.
