I havent had it happen yet but you never know what may happen over 400 miles of traveling. The local towing company says leave your car key outside and if you wreck or breakdown he can load your other vehicle up and bring it to you at no added charge. Then you can carry on with your vacation without renting a car. (insurance company will usually pick up one tow a year). Anyone else have any input or stories that took place on the way to the Burg?
