your just fundamentally wrong
first of all, yes some mountains have upwards of 2000 vertical feet on the east coast, but the snow quality just isn't there. the trails are MUCH MUCH icier, pow days are a rarity (i never skied a day of pow before i went to school in Colorado and i grew up in massachusetts skiing 40+ days a year min all around new england/the east coast), the pow that is there is heavier too. because the east coast mountains are much closer to sea level, there are NO trails that are above the tree-line, aka trails on the east coast are narrow and windy, trails in Colorado/Utah tend to be much wider and more clear, with MUCH more room to maneuver.
and dont even get me started on park construction/jump quality
