Allow me to reintroduce myself…
No, seriously, I just want to say one thing:
Wear. Your. Helmet.
My chain derailed off of a simple crub drop pedalkick tonight, resulting in the back of my head meeting the sidewalk. I was scraped up, but laughed it off and walked away simply because, for some unknown reason, I did my helmet up on the six-block ride. If I hadn't, I would still be in the ER right now.
One of the guys I was riding with was a spawnsored BMXer back in the day. He smacked his head in the Richmond park and split his skull open. Imagine having to spend 7 years off of your bike while you recover from that.
Please, take care of yourselves. An 80% recovery from a head injury sounds good on paper, but is quite disturbing in real life.
