3x5?
National Geographic profiled Cary, NC a few months back on the last page where they profile a new Zip code every month. They referred to 3x5s as the look-alike Colonial houses going up each with the same 3 rows of 5 windows each, or some thing like that. I'll have to dig it up...

Sorry, don't mean to offend any one; here in the office SJ and RTP jabs each other all the time. They, of course, laugh at our 3'x5' backyards here in SJ.
