Travel to seee all Nudist locations in the continental US

My basic plan is to divide the United States up into four quadrants.i have a Toyota Prius because it's very cheap on the gas and great as a camping vehicle.
Each trip around spend 3 or 4-month trip in each quadrant start Phoenix end up in Phoenix and then probably take a month or two to get prepared for the next quadrant.
What questions would you ask?
