A 35-year-old San Diego man got the gift of warmth for  Christmas after members of the Riverside County Mountain Rescue Unit and  California Department of Forestry found him shivering in his tent on the  Devil's Slide Trail near Hemet, a Riverside County sheriff's sergeant said.
      The man, described as an avid, experienced and well-equipped hiker began  his hike Saturday and failed to arrive at his pick-up point Monday night, so  his friends became worried, according to Sgt. Ron Lawler.
      He was found cold and shivering in his tent, according to Lawler. 
      Once escorted to safety, the hiker was treated for minor hypothermia and  declined further medical evaluation, Lawler said.
      The Riverside County Sheriff's Department reminds hiking enthusiasts to  carry proper equipment, including clothing, water, food, cellphones, maps and  GPS. More tips are available on the Riverside Mountain Rescue Unit website at  www.rmru.org.
