I was just curious to know the average size of the lawns in different areas of the country. While waiting for this constant rain to stop, I did some number crunching and came up with just under 18,500 sq. ft. average. This takes into account my smallest residential (1200 sq.ft.) to my largest (268,000 sq. ft.). I'm not looking for prices as that can vary wildly and I'm not so goofy as to post my pricing structure here. Any input is welcome.
