Went out for a early morning skate plaza session on my trusty two wheeler. When I headed out the door it was 20 degrees and it did not feel to bad. Riding BMX in the cool is rough on the body. the cold amplifies the possibility of pull muscles and seem to make the act of bouncing your body of of random object intensely painful. I managed to do both this morning. Pulled a muscle in my lower back and crashed enough time to turn my new pants into Swiss cheese. Despite the bad thing I rode very well and had a amazing time.
