I never leave the bike. I realize that is not the way many roll. My bike is pretty valuable, and the bags are stuffed with really important gear. It isn't difficult to have 10K with one on a tour, which is why it is probably a lot better to only have a few hundred, but that is how much some people spend on tires. I tour to ride, and see the scene. I don't really care about stuff along the way that takes me off the bike.
