+1 for the helmet.
This is my first year wearing a helmet. Last year I got knocked out with a grade III concussion, no helmet. I didn't even remember how I got to work the next day. I ended up getting taken to the hospital for a CAT scan.
At first I hated it and found it distracting. Now I don't even notice it. When I ride without it I feel like something's missing. And it def has the added benefit of keeping my head warm on windy and sub freezing days.
Now I look at few kids without helmets riding the park and think what an idiot, kind of the way I look at hockey goalies from the 70's.
