Tom...
It seems that those without OTR always travel north and south so the sun won't get into the windshield and on the driver/co-pilot.

If you recall, I do not have OTR either, but have an ample supply of right guard on hand.

Hope you guys have a great time at the eat-fest, tell everyone hello for E.J. and I. We would be there except we were just in Biloxi this past week, and E.J.'s grand daughter has her dance recital this week end in Dallas.
