I'd rather be on a bike than in a box in heavy winds. The mpg would be better anyways.
And to all yous that have never had your bike in a trailer or truck: I bet you have never broke down/flatted out either eh? I hear yous though. The problem with hauling the bike is that you have to haul the hauler to your next destination. One is chained to the cage.
Reminds me of an Otis Redding tune...
