My golf course keeps them stored for me all year long, it's kind of nice to not have the extra space at home for storing them, the kids clubs are super easy to keep at home and my wife's and mine stay out there.
Same place as during the summer. Just behind my chair in my living room.
I'm surprised by how many people keep their clubs in the car. Just no point in increasing the possibility of having them stolen like that. Sure the odds are incredibly low but it just takes like 10 seconds extra to bring them in.
