The early rankings were not accurate for me.
I am far more likely to be shirtless than barefoot.
Also, since I don't own underwear, when I got to undies only I was already butt naked.
My humorous comment for Super Nudist is that when you get there, you have to go into a phone booth, take off all of your clothes and emerge naked,
Similarly, once you achieve ultra nudist, you should move to a clothing optional resort and bring just one small suitcase of clothes, get rid of the rest and only wear any when you have to be off the grounds of the resort.
