Yep, I have to agree on the nudity thing.
You can go almost anywhere is the world and find clothed people. Malls, trains, work, swimming, hiking, sunbathing, beaches, rivers, water parks, amusement parks, monuments, showering... You name it and you can find clothed people. All people clothed - no nudity.
Those of us that like to find a place to loosen up and hike naked and swim naked have about 10 places we can go in the whole world. (Exaggerating, but it is very small)
Even here there are times that you may get the stink eye from a clothed person thinking to themselves, "oh geez, not a naked guy."
This isn't the place to go if you want to avoid nudity. It is the place to go if you want to relax in nature and free yourself from the cares of the world. Live and let live. Just enjoy without worrying about how others will effect your enjoyment.
That being said, weekends will have more clothed people I think, and from my perspective - I go naked on weekdays to avoid the crowd and the clothed folks that roll their eyes.
I think there is almost no time that you will find nudity free. At least one of us will be there, it's too nice of a place to go.
