It’s because anyone who is from the South grew up with every boomer-and-older-person inexplicably bringing up needing snow chains any time a place with snow was mentioned and overall treating the idea of snow as a completely unnavigable and extremely dangerous situation.

Everyone 60 and over in the south just loves to talk about chains. If you are traveling anywhere by car where it might snow, they ask if you have chains and make a this HUGE deal about it. And as is typical, they don’t believe you when you tell them they aren’t necessary.
