I had a bad crash after a 10 foot gator bit down on my bike while riding the Gainesville-Hawthrone rail trail. It was dusk and though I was using lights I did not see him till I was right upon him where he was lying beside the path. He turned and snapped down on the middle of my bike on the water bottle cage and down tube. I suppose he was either frightened by my sudden appearance or aggressive because it is mating season. The sudden stop sent me over the bars of course so I am pretty banged up. I will refrain from posting gory pictures for now. I was lucky, it could have been much worse. Please use extra caution if you ride that trail in the evenings.
