First off, the resort has to allow it - many in the US don't. You have to avoid snowcats, snowmaking equipment (do NOT ski over cords or hoses), and patrollers doing avalanche control work. Think of how it would ruin your day if the patrol was doing control work and dropped a slide or, perhaps worse yet, a charge on you.
I've been working control routes and had to wait for skinners to clear the area, which besides being dangerous for the people causes delays in opening runs. Major PITA.
You also have to avoid people going down the runs. Early morning before the lifts start spinning (and no control work) is usually the best time if it's allowed at all.
I just use the same equipment that I use to skin anywhere. Depending on conditions/mood it's one of my tele set-ups (1) or sometimes my (gasp) AT rig (2) which I generally pull out only for bc runs.

All have BD Ascension skins and I love them all. The NTN rigs are maybe a little heavy. I really should put up a picture in the shameless quiver thread, huh? I don't own any regular downhill equipment. Edited by Bob Lee - 12/11/09 at 6:53am
