About a year ago, some of the group I do trips with, stayed at a CG along Lake Tahoe the night before a bp trip into Desolation. The morning we were packing up, a FS employee/vendor/host came by, asked which site we had used, he was checking to make sure the fires were out. I had dumped water and stirred ours like it is supposed to be done.
I go off of the FS definition of an established CG, where there are picnic tables, sites numbered, metal fire pits/bbq's and maybe fees.
