Let's see...
Last crash was in February. Hit some cinders, used to give cars traction on snow and ice, and my front wheel went out from under me.

I really bruised my right side, so badly I couldn't walk, but luckily, I could ride. After I straightened the handlebars on the stem, I headed home. Only after I got home, did I find the crack right through the right side of my helmet. I also developed a good-sized goose egg on the right side of my head. I believe the helmet saved my bean.
