Agree with the observations on helmet use. Also completely agree with number 9. I've never understood the take the bike to the bar mentality.
Just an anecdotal observation, virtually all the bikes I see parked in front of bars are Harleys. Virtually all of the single vehicle motorcycle accidents I read or hear about are Harleys. I guess I do understand why most of the Harley riders I see in bars don't seem to have a helmet with them. After all, why risk destroying a perfectly good helmet.
Just another reason I generally choose to ride alone.
