There was also, until recently, a "western town" tourist attraction with a petting zoo and a functioning store.

The closure of the railroad, followed by the interstate's placement, largely accounted for the town's dwindling.

The racial makeup of the CDP was 75.86% White, 20.69% from two or more races, and 3.45% Pacific Islander.
