I'm both disgusted and intrigued.
The NYT has a story about dumpsters being converted to swimming pools.
From the story: "While the project is conceptually simple — get a bunch of trash containers, clean and seal them, fill with water, jump in — there were a lot of details to finesse. The coarse edges inside the containers were filed down, and underneath the liners, the bottoms were covered in sand, for soft landings. Tightly packed sandbags double as benches along the walls, and pool toys and kid-friendliness provide an intentional counterpoint to the neighborhood grit."
