I was heading west on RT.7 and there was an accident in the right lane just before turning right onto Potomac View. Had to get over to one lane on the left as the police cruiser was blocking the accident. Ran over road debris from the accident in which was not cleaned up, and popped my tire.Craftsman Auto Care is close by the intersection and luckily I was able to make it in, on the flat. Austin and crew were able to change my tire to the spare. I was very thankful for their service!!!
