WASHINGTON (WUSA9) -- About two weeks ago, Georgetown resident Greg Fishbin was scratching his head after he and his wife saw some people climbing and jumping on top of roofs, including theirs.
"We were like 'Get off of our house. Like, what are you doing on our house?' And they said, 'Oh we're just roof running,'" Fishbin said.
It's something that has a lot of the people in the neighborhood concerned and worried it could be a trend. One complaint was posted online and sent to the police- but this isn't a new thing.
Roof running or using something like a roof as an obstacle course is usually part of a fitness discipline called Parkour.
Mark Toorock runs the American Parkour Academy. He says he hasn't heard of this particular complaint, but he knows this type of thing happens.
