The last day has a texture the others do not. Everyone slows down on purpose. You stop sprinting between stages, you plant yourself near the main one, and you spend the afternoon deciding to be exactly where you already are.
That is the second Sunday: the closing day of the entire run, the last main-stage set anyone will play out here, and the strange hush that settles over a polo field in the Colorado Desert as it starts remembering that it is a polo field. The campground thins through the afternoon while people break down setups. The afternoon sets are the ones with nothing to compete against, which is usually when the surprises happen.
Empire Polo Club in Indio, with camping access ending after Sunday.
Go with the person you want beside you on the drive back out. The road home, sunburned and wordless, is part of the thing.
