Flutterby™! : need a new helmet

Coming down Eldridge Grade, through some of the rocky sections, all of a sudden the bike does something completely unexpected. Reflexes click me out of the SPDs, I go over the handlebars, land on my hands, tuck, kinda roll, the Camelbak keeps me from going completely over, and then there's a loud smack as my helmet impacts.

Stand up gingerly, still got full range of motion in the legs, cycling shorts are sticking on the right side, don't wanna know, right shoulder's a little stiff, feels like I pulled something in my hand, neck is strangely loose (brushes with death always seem to do wonders for my neck and back...), glasses still have their lenses, still have all of my peripheral vision, but... yep: the helmet has a big chunk missing.

Pick up the bike, and it won't roll. Hmmm... The front V-brake had pulled weirdly and was stuck under the rim, whence the "completely unexpected". Work that out, and I need to go to the bike shop and decide if I want to replace the pads and recalibrate the brake or just spend the bucks and go for disk brakes, so this can't happen again. I've been lusting after some of the features on Charlene's new ride anyway, but...

And I do need to get another helmet. And the shower I'm about to take is gonna huuuuurrrrt.
