Well, mostly I was just thinking about little things. Like cutting ridges in the floor right inside the doors (and maybe the windows if we're feeling carving-happy) to put salt in, that way when you open the door to go in or out or whatever, it just opens right over the salt line and doesn't sweep it away so you don't have to keep putting it down over and over every time someone goes in or out. Plus? Harder to accidentally break the line.
