I used to do the early season collegiate races in Florida. Most of us were just coming off of winter riding and so weren't back in the groove with large pack dynamics. The higher speeds and lack of pack riding practice made for some very harrowing crashes. The only times I ever crased in races was in Florida. Other bad things always happen to me when I go there, so I will never race or even ride there ever again.
Also, I believe that the off season for Florida is actually during the summer when it's just too friggin' hot be away from an air conditioner. Kinda like Texas.
