SAR Staff and the SVU responded to a location inside the SVU patrol area on the report of an injured dirt biker. The subject had been escorted out of the area earlier in the day, but could not figure out how to get to Lemmon Valley on the dirt trails. He then had a chain break on his dirt bike, and started to walk cross-country with the machine. He finally succumbed to dehydration, and called 911. Coordinates provided by dispatch were spot on, and the subject was located by SVU personnel. He was transported down to a waiting ambulance at Lemmon and Pompe where he was checked, treated, and released to a parent.
