Pulled up to my house just as it was getting dark. Noticed my neighbor 2 houses up had her floodlights on, and she is out of town. She was scheduled to be mowed tomorrow, but I felt like I had one more yard in me and plus I had Mr. Budlight as my co-pilot!! Yard is small, 15 mins with a 21 inch pushmower. We'll 1/2 way through the yard, OUT GO THE LIGHTS!!! Appears as if she had these floodlights on a timer. So now I'm mowing in the dark and going by instincts alone!! I'll check it out tomorrow morning.
