Thank you for all the info on swimming and sea bathing. It doesn't sound like much fun to sit in a tent in sea water, but perhaps that's just for the older folks. The backyard pond sounds more like a kid thing. Now I must admit to merely reading most of the boards without much participation. If I had tried to access the archives like any civilized person, perhaps I wouldn't have asked my questions outside the topic. But I did get to meet some very pleasant people in my search. Thank you. I will continue to read and maybe even post again.
