You do realize that you're using a computer to post on the Internet, right Ess?
FWIW - Mowing the lawn is a bit more than just developing a cultivated "machined" look to one's front yard. There are legitimate reasons for keeping one's lawn trimmed. The first thing that comes to mind is that an unkempt lawn becomes home to a number of myriad creatures that could be harmful to humans - rats, for one. Mosquitoes (possibly carrying West Nile), could breed in depressions a home owner couldn't see with long grass. Rocks, toys, etc., could be hidden in the grass, becoming a trip hazard - worse yet, if they had metal pieces on them, could become rusty and cause tetanus.
Add to that the fact that most grasses will die if left untrimmed. Nature has it's own way of maintaining healthy grasslands in the form of grazers... and I'm not really ready to have cows on my lawn, yanno.
My response to the original question: people who fashion themselves civilized (in line with Reb's answer). It's an overrated segregation that, much like religious fanatics, tends to limit more than enhance; any type of group that focuses more on governance than being proactive is nothing more than a false aid.
