If coming from the north then your best bet is probably in Petersburg, WV...I know there are some reasonably nice single-room hunting cabins just outside of town, and maybe a no-name motel or two in town. There are a couple diners you can choose to eat at, or hit mcdonalds, sheetz, etc. You ARE in the middle-of-nowhere WV afterall, so keep expectations low.
It will be cold, windy, and snowy on Spruce, so plan accordingly. Enjoy the hike!
