Vandalism to five cars over the weekend is causing some concern inside Great Smoky Mountains National Park.
Four of the cars were so damaged they had to be towed, while only one could be driven.
Park rangers said the vandalism happened at three different trail heads on the North Carolina side of the park Saturday night including Newfound Gap, Kenati Park and Thomas Divide Trail.
"Each one of the five vehicles had the windshield damaged and completely bashed in," said park spokesperson Dana Soehn. "When the people came out of the back country unfortunately what they found was a car no longer driveable."
Soehn said crime like this doesn't happen often in the park.
"This is a very rare circumstance, last time we had random vandalism was over 10 years ago," Soehn said.
Park visitors on Monday who were aware of what happened said it makes them think twice.
"I try to park away from the main entrance, obviously locking your doors and valuables and at the same time," hiker Matt Estes said.
Soehn said any valuables visitors have in their vehicles should not be left in plain sight.
"If they have anything valuable, they need to take it with them, or leave it at home or keep it locked in your trunk," Soehn said.
Estes said it's a shame to have to worry.
"You know, we are all out here to enjoy the nature and park and but that's the way our world is today and you have to take the precautions necessary to protect your things," Estes said.
If you know anything about this vandalism, you are urged to call park headquarters at 865-436-1200.
