Thought I'd revive this string. One place NOT to put the helmet is on the ground next to the bike at Chics by the Sea in West Haven, CT. We were up there on a chapter ride today and when we got back to bike, my wife and my Shoei helmets had been lifted. A couple of the guys in our chapter are very large and you definitely don't want to cross them. Let's just say that if we had run into those helmets on someones' heads, those heads might not still be attached!
