Uhm, I guess it kinda counts. I have a lake nearby too where I like to go swimming every now, and then so I know what you mean. It's amazing but, I find it easier than cold showers.
I never liked the swimming pools that much either, that chlorine was always hurting my eyes like crazy because I used to open my eyes under the water as a kid.
Yes, jump right into it, it's easier, faster, hehe.
Great to hear from you bud. :)
