I no longer own cable locks. We were at the Fringe Festival a few years ago, and locked our bikes up on the corner of Cedar and Riverside in Minneapolis (look it up if you don't know the corner). While we were enjoying the local theater scene in the Mixed Blood Theater our locks were tampered with.
The tumblers would not turn, I suspect glue, so we took bolt cutters and liberated our own bikes.
The cheap toolshop bolt cutters we used went through 14mm braided steel like it wasnt there. False hope is all that comes from cable locks I say. Now I carry a Ulock or a Forgetaboutit chain (or both).
Everything not bolted on I take with. Everything bolted on that I am leaving is locked down. two locks are better than one. I figure more than two locks attracts unwanted attention.
