GREAT!
Now Dive Local and Dive often. Yeah cold takes a little bit of getting use to, but it will really help improve your skills.
Dutch Springs is a great local quary in Bethlehem Pa. I’m sure your local dive shop knows of it. dutchsprings.com. But I would start by renting cold water gear to make sure you want to do it. There is a buddy finder on their web page or you could team up with us some time.
