My grandparents have a dairy farm, and my sister and I used to love to play there. We especially liked that people would drop off unwanted cats there, so we usually spent our time looking for cats or kittens to play with. On one of these visits, we asked our uncle who worked there if he knew where the newest family of kittens was currently hiding. After hearing they were somewhere behind one of the barns, we wandered off in search of adorable cuteness. But, there was a lot of manure to contend with. My sister was less squeamish than myself, so she crossed the manure lake while I opted to stay behind. She got about 4 steps before she began sinking.
I doubt I helped much, probably laughed at her predicament more than anything. But she managed to free herself and my mom hosed her off. When we told my uncle about it, he admitted that the manure is pretty deep over there, about up to his knees. And, he's a pretty big guy. My sister and I were about 10 years old.
