We were USFS hosts for several years. They would supply propane and all the firewood we asked for. Usually a pickup load would last us all summer. We weren't that big into campfires ourselves. We'd loan a bundle or two to elderly or handicapped campers if it looked like they needed it or said that they would enjoy having some. We never charged for what we loaned out. It's against the rules to charge for it and I think it's against the rules to give it away because if you give it to one you have to be ready to supply it to everyone.
What we had left at the end of the summer we carefully stacked under the picnic table at our host site and covered it with a tarp to keep it over the winter even though the camp ground was open longer than our stay. We actually expected it to be there when we came back the next year. LOL~! Talk about being wrong.
