I have to agree with everyone. This just shows it does not matter how short of a ride you are going on or where you are going to ALWAYS put on your helmet.
I had one time I didn't wear a helmet because i had girl on the back with me so I was going really slow and carefully giving her rides to the different jumps in the woods so she could watch everyone jump. At one jump we call the half pipe. I asked her to jump off so I could jump it a couple times. Round number 2 on it, endo, pinned under the quad while I was bent backwards and got a chunk of hair ripped out of my head where the back tire hit me.
I got lucky. DONT be a dumbass like I was once! Thats all it takes is that one time!
