Good luck! Cold water is... uuummm... cold.
I know that next time I do cold water swimming in a wetsuit, I want some neoprene socks to wear. My feet took the brunt of the cold and were so NUMB!
A nice hat to keep the warmth escaping from your would probably be nice too.
Let us know how it goes... Polar Bear!
