and check out these awesome anti-theft bike stands (via Bike Hugger).
My two main parking locations are at home and at work. At home, I noose a cable to connect the frame and the front wheel, then take the remaining loop in the cable and attach it and the frame to one of the posts on the front porch. Which you could saw through, but if we were home, such shenanigans would wake us up, and if we weren't, the dog would have a full-blown fit. She's a love, but she can sound quite ferocious. At work, it's the same strategy, only I'm locking to some huge metal pipe that comes down the back wall. If I stop at the grocery, the bike gets locked to one of the cart corrals, and all the peripherals go in with me. (Which always confuses the checkers and baggers--yes, I KNOW there is stuff in the bottom of the bag (my pannier). Put the groceries in anyway!)
A friend emailed me this op piece on why Sarah Palin is scary, and not to be trifled with.
