We were stuck on the I77 West Virginia Turnpike Mile marker 66 during the storm for 12 hours before we left to go back north to Charelston. The Espar made it pleasant and we did not worry about consuming fuel. Having a 4x4 van made traveling a little easier also when we headed back. Sat in Charleston another 12 hours and started back south before they opened the turnpike so we could beat the rush. This is another time that the Espar proved to be a great item to have in a van.
