My guess is he probably was wearing a helmet of some kind. WA has a helmet law, as does nearby OR (just across the river from where this happened). I haven't seen any helmet law flaunters around here, even on cruisers. The squids up here are pretty good about wearing a full-face lid, even when they're in shorts, wife beaters and tennies. Pretty rare to see a sportbike rider with a beanie or nazi lid.
