Any time a camper occupies one spot for two months they will have an impact on their surroundings that could take a fair amount of time to disappear.

If you do camp in one place for that long, you should definitely choose a place where the damage has already been done. In other words, where the tent site is packed hard by countless feet and the trail to the water source has already been established in the same way.

Then there are issues of whether or not you will be burning wood, and whether you are depleting the wood supply for campers who come after you. And the issue of squatting in a spot where other campers might legitimately want to have their own turn to camp there.

A two month stay in one place is a lot to ask. You would be better advised to stick to the two week limit and adjust to moving on from time to time. Those rules are not arbitrary. They have a purpose.
