In the south it’s also more common to either not have a garage at all or have a carport instead of an enclosed garage. It’s just easier to leave your car or vehicle (tractor) out anyway. Combine that with, I need to sell this or work on it at some point, you park it in your yard and will get around to it someday. Or maybe your cousin might need it one day so you’ll keep it. It’s a bit of an ingrained impoverished idea that you “might need it someday” attitude.

I’m also staying with family that are regularly using tractors pushing 60? 70? Years. I’m not even sure how old they are, but it takes a bunch of parts and pieces to keep these things running. Luckily here though the scraps are either off in a barn or not directly in between the house and the street.
