Mammoth is a good time, spring skiing was amazingly good when we went in May. The snow was corn goodness, they stayed open 'til August in 2023! The staff made that happen, and that's the intangible which make the place special, the spirit of Dave Macoy? The Eastern Sierra? For the love, something though, its a happy mountain with really helpful and cheerful staff, people are generally stoked (and in this day and age (its gold). Demo ski set up best I've ever seen, all top bands all new, can swap out with ease at 4 locations.
