I always thought the jeans-in-boots thing looked dumb, but I didn't know it was an actual style. It kind of just happens when I pull my boots on and don't bother with my jeans. It helps keep the jeans out of the mud. If I want to look appropriate, I pull my jeans over my boots. When I'm in a hurry and I don't care, I don't bother pulling my pants down around my boots. Didnt think it was a style though. Just thought it was laziness or a way to keep the dirt off your pants.
And those who were seen dancing were thought to be insane by those who could not hear the music
