So, my friend was coming by my house to drop off her son to spend the night and hit something in the road near the high school about a mile from my house. As she pulled into our subdivision, she realized her tire was flat. Whatever it was, punctured a pretty big hole in her tire. So, her son and mine changed her tire. Only took them about 15 minutes. About half of that was getting the spare tire lowered from beneath her van. They do pretty good work for a 15-year-old and almost 15-year-old!
