Road Trip #331 - I-85 North - North Carolina Mile 226 to Virginia Mile 15

We wrap up our fourth state in this series as we approach the North
Carolina/Virginia border, beginning at Mile 226 in North Carolina. We
encounter an accident on the highway due to a tire blowout, and then
enter the Commonwealth of Virginia, entering Mecklenburg County. We
cross Lake Gaston, and pass through a rural area, ending at Exit 15.
