simply, federal law you cannot profit from personal use of gov. lands without payment, permit. You can with a use. permit such as firewood, personal or commercial, .
Commercial for profit use of federal lands are by license only. A camp in the Black Hills that led horseback rides thru the forest was bankrupted for lack of license, permit.
On our last winter sojourn to backcountry Az, where 4x4 sxs were prevalent and camps led paid guides to lead guided tours all over the BLM lands I arose the issue, to the camp owner, he immediatelly ended the practice
Gov. lands are all ours, where they are impacted by the few
there should be protection and compensation for use of our land.
