I hope I'm spoiled up here in the next couple winters. Everyone gets hyped in the midwest if 8 inches is on the table. I can't imagine something near 20 inches. The largest storm I ever experienced in Illinois was about 14 inches. Believe it broke the record in Springfield, IL for most snow in 24 hours with like 17 inches or something. However, the deepest snowpack I've ever experienced was in Idaho this winter. Was doing some research during a project up there in the mountains and the snow depth was at least 3-4 ft everywhere. I was absolutely in awe.
Edit: Sidenote, I asked some locals up there how late in the year they have seen snow and they told me they got measureable snow on July 4th before. Truly incredible. To be fair though, last year was a year of epic proportions for almost all of the inter-mountain west and west coast mountains.
