Note the hitchhikers on my right arm and jersey in this pic. For non-desert folk, those prickly green things are cholla cactus segments. This picture was taken last weekend, at the 1st Round of the "AMA National Hare Scrambles Series", held at Mammoth, AZ. I happened to hit that cactus at about 30 MPH, which left needles buried 1/2"+ in my bicep. I'm still displaying some good bruises. I did eventually have to stop and remove some of the cactus (using a race marker), because the pain was pretty intense.
