Hardwood floors are a thing of beauty when dancing to Bob Seger's "Old Time Rock And Roll." The most beautiful homes in the world usually have lovely wood flooring polished to a high shine that little kids love to skate on in their socks. Come to think of it, some adults love doing it too. So prepare to slide around on gorgeous hardwood floors in sexy underwear like Tom Cruise did in Risky Business. But please, keep the drapes closed.
