At what point do travelers switch from camping to living off the land?



Hence the need to identify the gotcha rolls.

I would say Camping is when your well supplied and any hunting or foraging you do is for variety and fun. Or even to stretch your supplies.
Living off the land means all your food and water come from your rolls.
