OK, maybe all y'all do this, but I just figured it out. I was in Florida with all my crazy family for a week, and I took my bicycle (which didn't cost me one red cent on Delta!). We stayed at Navarre Beach which is still recovering from Ivan and Dennis, but it's lovely. I digress--Anyway there is a bridge with absolutely no shoulders at all which you must cross to get to the mainland where there are nice shoulders and even bike lanes. Of course, crossing the bridge is horrifying as the cars pass you when there are other cars approaching. After seeing my life pass in front of my eyes a few times, I decided that when there were other vehicles approaching that I'd take up a position right in the center of the lane so that they couldn't pass me. Then when the coast was clear, I moved back to the right. It worked out pretty well. I did have one honker, but I just let her wait. Whenever I was moving to the middle of the lane, I put my left hand down and out in a "stay back" sorta movement. Anybody else try this???
