No one likes obnoxious city slickers yammering into cell phones in the tramline. But we also recognize that working via satellite may earn you an extra powder day or two. Such is the logic, anyway, behind resort WI-FI, which may just be your ticket to getting the job done remotely-without announcing it to everyone on the mountain. Squaw Valley and Whistler have both gone fully wireless this season. Stuff your G4 in your pack and log on from just about any building, be it the mid-mountain lodge or base-area brewpub. Your boss will be none the wiser. And fellow skiers won't be tempted to clobber you with snowballs.
