I can imagine that from a farmer’s perspective it could feel like they have one long conversation with the same camper, who happens to wear many faces. For the camper, they, the spot and the night are unique and special.
Booking camp sites ahead is a pain if you are just one person with a car and small tent, but must be more so with a bike. I have passed up sites where they wanted to charge me the same price as a family with a mobile Nissen hut. However, if you are midweek or off peak, you can often just turn up on sites whose websites say “prebook only”.
The farmer wasn’t just an idiot for filming himself….but how the heck did the footage get out? He must have shared it with others who shared it further. Really stupid.
