If you are genuinely interested in reading stupid-racist stuff, just patrol this board for a while. I never cease to be amazed at how many conservatives here are overt racist swine.
As to lawns, we live in a desert. It is just stupid and wasteful to try to import the Midwest and have a big ass green lawn. In Tucson, we did not have a single blade of grass, but we had rock gardens and desert landscaping...and it looked freakin' awesome!
