I've done the Tour of the Litchfield Hills in CT and it seems for the most part that the kamikaze pilots are self regulating. Those that want to hammer usually just go right from the gun, so hanging back a bit allows you to avoid the craziness. Normally I get chatting with someone at a rest stop, and maybe ride with them for a while if they're at my pace. I'm contemplating doing the Bike Tour of Colorado one of these years and wondering how the testosterone level is there where the hills are longer.
