WEAR A FRIGGIN' HELMET!
And a damned full-face helmet. Open Face = Closed Casket!
Scooters are small and hard to see.
To add a litte perspective, back in th early 80s everyone
over age 15 (edit, back then you only had to be 15 to get a Moped license, in my town age 15 was when we started being allowed at the giant keg parties, so that was part of the moped/ scooter issue back then just like Iowa City today)and above was riding Mopeds, to school, to parties, to work, and often in groups late at night... I do not recall seeing anyone ever wearing a helmet, and despite a lot of poor decision making, I do not recall any big incidents.
Back to today, if you ever drive by the Gopher Football Complex on 15th St, even in cold weather, you see a large number of scooters. At least half the football players have scooters. If you spend much time driving around campus (I work nearby) and recognize Gopher players without helmets on, you will see a bunch of them near your car, on scooters.
As far Iowa City goes, they have an extremely aggressive police department, acting on a mandate from the top of th U of I to crack down hard on all things alcohol related, and U of I athletes are in no way overlooked or given any SEC type special treatment.
At the Universit yof MN, there is nothing approaching the Iowa heavy handed enforcement situation, and there is also the added benefit of being more invisible, even as a DI player in Minneapolis. In IC they actually hand out public intoxication to students who are walking around, and not especially intoxicated. That never happens here.
