Tile-
Our kitchen is down and my fridge in right next to the front door. That's convienant when I come in and need to put the milk in the fridge quickly but that's about it. I have to tip toe through the kitchen to get to the family room or garage. Kinda like Indiana Jones in the 3rd movie where he is going for the grail and if he doesn't step on the right tile, he falls though a chasm. I don't know when he couldn't just tap each tile to find the solid one.
