Rode from Phx. to Casa Grande this morning and back, nice ride but mildly windy, maybe 8-10 mph. Lots of 18 wheelers on that stretch between Phx. and Tucson, I-10, most doing 70-75 mph. (speed limit is posted as 75) I couldn't believe the damn buffeting I was getting when passing! And when passing at the speed limit in those occasions when the truck was going slower, just prolonged the agony. I finally started increasing my speed to 80-90 mph just before initiating the pass, just to get it over with quickly. I've ridden a lot and for many years, but have always avoided interstates when possible; find them about as interesting as watching the grass grow. But any tips anyone might have about how to handle 18 wheelers would be appreciated. By the way, I don't like to be close to them due to their propensity for shredding tires and leaving debris in the road. I also have a close friend who caught a lug nut from one of their wheels on his helmet at about 90 mph. Ruined his helmet and would have certainly killed him had it hit his face plate rather than the helmet.
