don't have to "control it all" ...we are talking about a couple of KMs on a few (5-6) stages...2-3 rotating groups of Gendarmes stationed at strategic spots and a few well-publicized arrests/fines of serious violators might make 'em reconsider running between riders waving flags..(what if one trips and falls in FRONT of the race leader?)

Sorry...I appreciate enthusiastic cheering, but if they want to be IN the race, let 'em get a bike and practice. Those guys in the Devil costumes don't add much to my enjoyment of a BIKE race.

I have more than once seen riders wave off and gesticulate angrily at rabid fans (didn't one get repremanded for whacking a fan last year?)
