Carrying skis and snowboards inside your trunk equals dull edges and a snowy mess after a gnarly day of shredding pow pow. We should throw a bro in there somewhere. At any rate, as in most sports, the rule of the day is that people go inside the vehicle, gear goes outside, or else everyone gets a damp bum in the winter and a sandy one in the summer.
Yakima winter accessories snap around the bar quickly and easily, and are all lock core compatible so you can create a chain of security: the rack to the car, the accessory to the rack, and your equipment to the accessory.
Don't forget that a Yakima cargo box of the proper length can be the best ski or snowboard rack ever. It keeps the salty road crud out of your bindings, which means they'll release when they're supposed to.
