You betcha! I think it all goes back to a couple of things relating to my childhood. The street we lived on had a low place that collected water into a huge puddle after a hard rain. It was always a lot of fun to get up speed on a bicycle and hit the puddle spraying water everywhere. Also, we would camp a lot at a nearby reservoir and sometimes it would rain. If you're swimming, it doesn't really matter about rain, of course lightning is something else entirely.
Yes, I love having fun in the rain. I also love dancing in the rain and so does my hubby so when it rains sometimes we go dancing in the rain together.
My husband's parents raised him to absolutely love dancing in the rain! They never allowed him to go outside in the rain when he was a kid, lol.
