Two years ago was a fantastic season in the Sierra. Crazy amount of snow. Last year, not so much but better than many. The Ikon Pass is new. Boot soles that aren't compatible with all bindings, bindings that aren't compatible with all boot soles. More narrower skis, more mid-widths that are doing more, better.
The Epic gathering in Tahoe a number of years ago was some of the best skiing I've ever had. It wasn't blower pow, but I remember comments that it was drier snow than typical and it skied wonderfully. I would love to be able to get back out to Tahoe soon.
