In the Fall we get very heavy dew on the Canadian prairies.  So heavy that you are guaranteed to have a wet bum if you sit on the cockpit seat.
Its very slippery too.  This is the time when the migratory birds test their new flight feathers.  The young geese follow mom and dad
on daily flights around the lake to learn about flying in formation for their long migration south.  Nobody knows why Canada geese honk.
