I disagree, boxes can be a lot of fun. Plus you can spin across boxes unlike rails. They're great for learning too. I learned 270 on and off, on a box before i did them on rails. As an added bonus, boxes don't normally fuck up your skis.
i think that boxes are only cool if you do things that would be near impossible on a rail. and i managed to spin a 180 on a rail at high north this summer, just like you would do on a box
boxes can be really cool and very technical tricks can be thrown on them i think it is cool to see pros throw down on a box just as cool as it is to see them hit up a rail anyways
