The
Society for Creative Anachronism does historical re-enactments with varying degrees of authenticity. These range from small teaching events to large "wars" involving thousands of people.
As you might guess, that many people generate a lot of garbage and other waste. There is trash to be hauled away, and there are portable toilets that need to be serviced. There are vendors preparing and selling food from tents in hot summer temperatures. There are men out in the sun, dressed in armor, hitting each other with sticks, and there are waterbearers and various safety officers visiting them during breaks to keep them from getting dehydrate or overheated.
There are banquets to prepare and to clean up after. There are numerous pavilion tents to put up at the beginning of the war, and they need to be taken back down at the end, sometimes in pouring rain. Speaking of rain, there are drainage ditches to dig to keep the rain from flowing into tents, and those need to be filled back in before the camper goes away.
An SCA war has a lot of interesting things to see and do, and there are a lot of dirty jobs going on behind the scenes to make them work. And what's more, 99% of the SCA's dirty jobs get done by volunteers.
