Have you ever strapped your boards or kayaks on your car then drive away to hear a super annoying vibrating sound that even the best car stereo can't block out? This is caused by car rack straps that are not twisted - twisting the straps prevent the noise. Sometimes strap ends will do it, but usually not as as annoying as the main straps.
The last time this happened to be, I had two stacks of boards on top and while the straps were twisted, it took me a few pull-over's to find the right one, which of course was inside the two stacks in a difficult to reach spot.
