Went to Mammoth to ride the mountain bike. Been doing a lot of trail riding to get in shape for hunting season. Did a major 2000' ascent a several down hills and climbs. At the 15 mike mark a rock jumped in front of me and left me eating dust and gasping for air. Pretty sure I've broken some ribs or atleast severely bruised them. Had to ride out another 5 miles to get back to the rig. I can't even lift my bow let alone think about drawing it. $&@%#*€&$
