YA'll are SO FUNNY! I had a crazy roller accident involving a wall and a dog. Riding on the rollers oblivious to everything except for the digital clock on the wall counting down to my final minutes, went for an all out sprint , before the cool down, when my dog entered the room, I must have looked crazy to him so he jumped on my back! I went flying off to the side and right in to the wall! Left a 2ft streak down the wall with my head! Everything was quiet except for the spinning of my rear wheel, the sound was deafening! As I slowly opened my eyes i could make out a shape, as the image got clearer , I could finally make it out as the dog who was sitting there looking at me. I might have been delerious ! Because the more I looked at him, It actually looked like he was laughing at me!! Damn dog!!!
