I don't think I'll be able to manage that even when I get *really* fast. :) The front yard is an obstacle course of trees and bushes and other topiary, and while the back yard is mostly flat and square, it's fairly good-sized, and I doubt I can cover it in less than 15 or 20 minutes. Still, who knows what'll happen once I get the mower up to the top speed. Wheeee!
