during the summer i built a sun shade out of 10 foot conduit and used a piece of camouflage canvas that was the only size canvas available in 10 X 10.
when it rains, i sit under it with my cigar and coffee and listen to the rain drops.
my question is when the helicopters fly over, and they fly low over my yard, do they see a 10 x 10 void in my yard? do i have a bermuda square?
