How Early is Too Early To Mow Your Lawn?

I recently saw a post on Facebook from a friend who was frustrated over her early riser neighbor's passion for lawn mowing.

My neighbor started mowing her lawn at 6:40am. I find this very rude. Thoughts?"

We had a variety of calls, but the general concensus seemed to be that 6:30am is too early. Many callers sited their various town ordinances and other's said it was about respecting your  neightbors and was dependant on where you live.

We moved the conversation over to facebook and many of our listeners had some pretty great points to share. Overall though, I'd say I won this round ;-)
