What’s in a Name?

There is a place on the edge of town beside the river, where ski bums bed down two-by-two like cord-wood. Visions of powder turns dancing through their heads, all cozied up before their next big day on the mountain. This place is called Dream Island, a trailer park just downstream from the aromatic sulfur springs.
