And some just leave their grills there...hoping they will still be at their fav campsite next trip....the grill to heavy for any person to pack it out willingly.

I stayed at an unmarked site that from the water looks terrible on Russell.  I bet most people wouldn't even get out and look.  But once you're up in the trees...this place was somebodies home...heavily used...many amenities, obviously for future use, and I'd bet multiple times/year by certain groups.

I found it very homey!  Felt like leaving them a note to bring the fridge and TV so it be there on my next trip!
