A cement floor with an outside drain would be easier to just hose off. I currently have vinyl but still have to scrape the droppings off it with a hoe and when I hit it with a hose, I have to be careful it doesn't get under the vinyl and rot the floor.
Life is a rush into the unknown. You can duck down and hope nothing hits you, or you can stand tall, show it your teeth and say "Dish it up, Baby, and don't skimp on the jalapeƱos."
