I haven't actually been dismounted yet. Came close a few times though.

#1 There is a gravel path that I have to take in order to climb up the back side of the park to exit out onto a main road to continue on to the college. I rode over it the same as I always do one morning before the work crews started there park maintenance. On my ride back I rode back through the park like I always do. But this time when my front wheel hit the gravel path it slipped and the whole bike slide sideways. I dropped my right foot and dug in like I was stopping on ice hockey skates. When I looked down I noticed it was all new loose gravel. Before that day it was all packed down real hard from all the park maintenance and ranger SUV's that drive over it. Actually it was more like cobblestone than gravel.

#2 I was ridding through a residential neighborhood and a car rounded a corner behind me with some speed.(some residential streets actually have speed bumps installed in my area) It came off a main road that runs parallel to the street through a short turn off. I instinctively took a fast peek over my shoulder while maneuvering closer to the curb when I felt the *THUD* on my helmet. (tree branch) It all happened in a couple of seconds I just reacted in the split second moment. It didn't knock me off the bike or hurt. It did leave a dent about the diameter of a quarter on my helmet though. I'm not sure what I could have done there. It happened *snaps fingers* like that. Luckily I had some foam wrapped around my skull.
