The Midway Mall in Big Piney usually sells bundles of firewood for campfires and stuff. On the Pinedale end of that unit you are closer to the National Forest, but the general store that used to be Faler's (and will always be Faler's in my head because I can't remember the new name) usually sells bundles, too. If not the Sinclair gas station usually does. They are kindof spendy, but probably handier than running up to the mountains to scavenge for wood. Both of those places have hunting supplies, too. The National forest is pretty close to Big Piney and Kemmerer also. I guess pretty close is kindof a relative term. Watch out for burn bans, though. I haven't been paying attention to burn bans in that area. It seems weird because they had snow last week, but sometimes they still restrict fires to established campgrounds.
