What about a nice and steady stream of good pow on the day of? My last day at Tahoe was like that. Over 2 feet total that day. Visibility left something to be desired, but man the snow was sooooo good. My first real pow experience.
Word of caution, if you have never ridden pow or up at a high elevation, it can kick your ass. Slowing down mid-pow run is not a good idea lol.
