A 15-year old boy was bitten by a rattlesnake in San Diego Sunday.
Firefighters were called to Fortuna Mountain in Mission Trails Regional Park area where the teenager was hiking with a group of people.
The San Diego Fire-Rescue helicopter flew in and hoisted the teenager out, then flew him to Rady Children's Hospital.
Firefighters say it's unusual to see rattlesnakes this time of year, but they could be appearing because of the drought and high temperatures
