Residents from across the territory, including Twenty Mile Road (18 delivery points), Highway 140 E (9 delivery points), and Plush Adel Road, collect their mail at the post office. One rural route and one highway contract route serve the scattered ranches and homes.

Historic Housing Patterns

Of the 78 total housing units, 60 are occupied year-round and 18 are vacant. Another 12 units are used seasonally or occasionally, hinting at the occasional weekend rancher or hunter passing through this isolated corner of Oregon.
