To the moon!
I was sitting at a table with a couple other people and my Father suggested that I mention the seas I've swum in. I wondered why and started listing the Pacific Ocean, the Atlantic Ocean, and the other places. Then my Father mentioned Tranquillity, and I remembered :) I was on the moon, in the Sea of Tranquillity, with a video camera in hand, doing a mini documentary for the viewers. My partner was assembling the habitation module, and he was almost done. I showed the viewers the little concentric frost rings (though some of them were rather large) which showed that there was moisture on the moon, but only in the permanently shaded places like this. The larger rings were fainter which showed that they were older, and that more moisture had been here previously, and may come again. My partner finished the habitation module and went inside to sleep, he was very tired. I relaxed :) I pulled off my gloves and my boots and my helmet and lay back on the lunar surface, happily breathing the non-existent atmosphere, watching ice crystals form from my breath and hang there, suspended in the micro gravity :) It was lovely :)
