Reason #88 to rent a car for long trips. Be sure and rent from a major name rental agency, i.e. Hertz, Avis, Enterprise, etc.... If the rental car craps out mid-trip, they get you into another car PRONTO. No muss, no fuss.....I have taken my family on several thousand mile plus trips using a rental car and I'll say this; my blood pressure remained nice and low during the trip.....
