Pinelander, From the SLC airport you are about 30 to 45 Min's to get to Alta or Snowbird. You will spend less time traveling and more time skiing in Utah. There should be a lot of flights from all the bay area Airports The Cottonwood Canyons hold late season snow very well. Snowbird will be the last place to close for the season. I would check Alta for a closing date.
By the way what part of NJ are your from? i grow up in South Jersey I guess you could say I'm an escaped "Piney"
