I almost never remove my bindings. Not when I wax, not when I store over the summer, nothing. A lot of people are worried that the base of their board will develop dimples from the binding screws, but so what if it does. Are barely perceptible dimples going to impact the way it rides in any way? Nope. If it makes your board easier to store, take 'em off. If it doesn't, don't bother.
