I am surprised that they did not take out their rulers and make sure they were 6 feet away from each other.
Well every country has it's own rules. Czech Republic's say you always have to wear a mask if you go in public (wich is not such a bad idea accordimg to a lot of scientists). The US rules are valid in the US only. So what's the problem? You can read the Czech rules here (in English): Handbook for citizens: Rights and obligations during a state of emergency – Aktuální informace o COVID-19
Generally speaking, If it means we should wear a mask until we get past this virus, that’s fine as I fall into the senior age bracket. If Chlorine and disinfectants are used properly to kill germs around pools and hot tubs, it sure would be nice to see some nude campground/ resorts reopen. Can’t wait to be socially nude again.
You don't need chlorine and desinfectants, usual soap does it. The SARS-CoV-2 virus has a bi-layer lipid envelope that gets destroyed both by desinfectants as by soap. Also, you don't contamine via surfaces, but by getting virus-loaded spray on your mucosa, for example if someone infected coughs or sneezes right in front of you. So distance and / or (if niot possible protection (masks etc.) makes it. But in these days i would prefer to go out in plain nature alone or with few people than to meet a lot of people in a venue. You also might be a danger for others, as you may emit the virus after a "soft" and unnoticed infection (scientist think there is a dark figure of 800-1000%). So wearing a mask is a protection for you as well as for others.
The point that was missed was that with all that is going on, the Czech police found it necessary to bother nudists who were staying AWAY from others. it wasn't about a handbook - simply common sense.
