Spring skiers are happy denialists. Nevermind that it's 65 degrees at the base lodge, that even the open runs are patchy with grass or that the snow is a sticky, mashed-potato-like slop. You see a sad, half-melted mountain and an excuse to break the bike out of storage; they see the glorious resolve of one season against another and the year's first opportunity to wear a Hawaiian shirt.
The joy of spring skiing is in its contradiction —doing a cold-weather sport in warm weather is just inherently fun, no matter what the conditions are like. You don't need a garage full of specific gear to do it, but it does present an opportunity to kit up in things you wouldn't have worn back in January.
