Ha! I had just moved into my new home with 1900 sqft of basement that I had plans to set up as a machine/motorcycle shop (my hobby at the time). About two weeks before I was going to do the black and white checker pattern for the floor I was exposed to model airplanes. The provider of my children put her foot down and said "tile or airplane!" I must admit it took me a few hours to decide that one.
Now I have a workshop as big as most hobby shops but the floor is still plain cement.
It does make for a great treasure hunt when I sweep.[sm=bananahead.gif]
