look at the bright side all the big ones made it to the house before you started to mow. Getting close to winter and they are out looking for a place to stay comfortable.  Usually when you spot one this time of year there are 50 that have followed the trail already.

    just kidding,,   my wife stops the mower and moves them out of the way or carries them to the garden.  I do it with a sharp shovel,get to carry twice as many that way.
