...it's a plane.
Indeed it is.
I love walking in the neighborhood very late at night with Max, our "three-poo," and looking up at the night sky. It's dark, but as we live in the suburbs, we can actually see stars, instead of a mulitude of high voltaged lights. (contrary to Toronto's downtown business core)
One of the neatest things I love to see is an airplane cross the sky, his headlights on as he skims the inky dark. Those headlights/high beams cut swaths of brightness across its clear or cloudy path, just as a car does while driving on a lonely stretch of road.
Truly a sight to behold...
