Just curious... speaking of falling... I took a mighty spill Sunday at Alafia. I was going a little to fast on a trail that I was completely unfamiliar with. Anyway, I went over the bars and rolled out with only a few scratches and a nice-sized lump on my inner thigh. Interestingly, I had just re-read an article about falling where you use your arms to control the direction of the fall, but you allow your elbows to bend so you don't bust a collarbone. Then you roll over a shoulder to dissipate the forward momentum. I would say that in a "def art" sense, my fall would not fall into a "classical master" category, but hey, no broken bones, and I was able to keep riding -- the hallmark of a good fall in my book!!
A question arose though as a result of my fall -- the insides of my helmet "broke free." The part that came loose was not the actual helmet, padding, or foam, but the plastic part that tightens around my head. It appeared to come apart toward the front where each side has what looks like a breakaway connection. I could pop the pieces back in place, and my helmet feels just like new (i.e. I can tighten it without it popping out). I think I might've heard somewhere that you should replace your helmet if you take a hard hit, but I'm not sure... does anyone have a thought on this?
