I recommend, "Strang Days Indeed" by Stuart Ward. It is written from a perspective in the future, about the present, which was I think, 2008, when the book was published.
Folks of the future are freely nude as the norm and looking back, telling their wide eyed grandchildren how strange it was back in the day.
A Naked Bike Ride demonstration has taken place, which begins a spontaneous eruption, a chain reaction. We read as the world flowers with naked bodies and that freedom. It is filled with interesting perspectives and twists of naturism and nudity. It should be difficult to read without pondering, "What are we thinking?"
Warning: This was written by a vegan who lives around holy Mt. Shasta. The book also reflects his other passion, that veganism.
Anyway, it is a fun book, a rich cheery fantasy. It's probably time for me to read it again.
