I am sharing a photo of this rusted tank for the Ocean's category. Why? You can find this tank (and others) on a beach. It's just sitting there in the sand, getting slowly washed away by the water, getting more and more rusty. I think it's quite fascinating. These tanks are there since the war and after the war ended, people just left them there. That's quite a piece of history that you would not expect if you are just thinking of going to swim. The photo is taken at a beach on the island called Culebra. That's a small island just off the coast of Puerto Rico!
