I just bought the clipless pedals for my mountain bike at the same time i got them for my road bike. So I am used to not being clipped in while mountain biking. So I fell 5 times when I wasn't able to clip out fast enough. I guess it wasn't that bad since the only one there to laugh at me was my dog and my buddy that was behind me, but the cactus i stuck my hand in while falling wasn't the best feeling.
