We boot up at the car, then lock the boot bag to the ski rack by the base lift. That way we have a place for gloves, layers, goggles, snacks, water, tools carry straps etc. We use a small ski cable lock and thread the wire through the two metal zipper pulls and then the ski rack. We have done this at multiple resorts for multiple seasons and never had an issue with theft or tampering. For folks like us who like to maximize their slope time, it is a great solution. It's like having a private locker right next to the lift. It's especially noce not to have to run back to the lodge or car when you need to shed a layer, change gloves or just swap out goggle lenses.
