I carry mine in a computer backpack I got from Target. It survived it's first crash this past Monday when a car got too close, and I tried to move over... getting my wheel caught in a crack between the asphalt and the gutter. Went over on my side, tore my pants, bruised myself pretty well, and skinned a knee. A few scrapes and such on my bike, but overall everything came out fine, including the laptop. I took it easy the rest of the way to work (another 8 miles or so) only 5 minutes late, and took a couple days off riding to heal.
I'll definitely be a lot more likely to NOT move over when I'm already that close to the side of the road... there was plenty of room for her on the other side... not sure why she was quite so close.
Several motorists DID stop, and make sure I was ok (nobody bothered to get out of their cars though... once I got up and started walking my bike, they all continued on their way).
Ah, the joys of riding!
See y'all out there tomorrow!
