Welcome Barbara and Couch Potato !
I am from Brooklyn, also. (Park Slope)
You will love it here. Try to get your couch potato to come with you.
Here's a list of all the clubs. Maybe he'll find something of interest.

My husband is not a joiner either, but I love the fact that I can enjoy so many activities.
Be sure to consider resales when you look. You can find some really great deals.
But compared to NY, prices here will be unbelievable.
I would recommend the LSV. Sales people have a wealth of info and NO pressure. Also, agree that getting a Villages map ahead of time is very helpful to determine the neighborhoods that you may prefer to live in.
