Welcome Sue from Northern California!
I lived in the Florida Keys for 2 years so I know you are not used to the cold. Here, a really cold day is in the 40s but luckily pretty rare and you should see all the heavy clothes I wear. I only want to be in snow when I go on purpose, for a fun vacation.
You will learn so much here and make friends too. Enjoy and participate. You can share your knowledge and remember that if you have a question, somebody here is surely wondering the same thing and is grateful when you bring it up.
