The photo of my Bridgestone errand bike above in post number 55, you can see that there is a thin cable wrapped around the seatpost. It is not much of a cable, but hopefully it is enough to prevent that kind of loss. That bike has a quick release on the seatpost, but a thief would also need to have a wrench to disconnect the cable from the top bolt that holds the saddle to the seatpost.
When I toured Pacific Coast, I also used a cable like that to physically attach my Brooks to a bolt somewhere on the bike frame. On that tour I was concerned about theft in the campgrounds.
