You'll find Billy, Dave and the rest of the Hardbooter crew in Park City mostly and Phil is the head coach for the PCSB alpine team. Look 'em up!
Where to ride? Well, if you're staying in SLC, take your pick! Brighton, Soitude, Snowbird...and if you do the two-plank thing, Alta ( - directed to one of four hold-out resorts) You should take a day or two ride PC and/or the Canyons. Plenty of choices! You've picked a good time to come to the area and you will probably encounter a variety of riding conditions. In other words - BRING SOMETHING FOR POW!
Night riding - Brighton!
Though 4wd can come in handy, you should be fine with a front-wheel drive. A REALLY heavy dump can shut down the Big and Little Cottonwood Canyons for short period of time (hours), but these roads are generally well maintained. Same with I-80 to PC - not generally a problem. Yes, they 'Recommend' 4wd and/or chains - but the NEED is more of an exception rather than the rule in my experience. The state transit authority (www.rideuta.com) has bus services that go up Big and Little Cottonwood Canyons (Brighton, Solitude, Snowbird, Alta), not sure about SLC to PC - probably something available.
