also remember the first line of defense/offense is to tell them to stop using your yard....which means a face to face encounter and 95% will not do that....but will easily sit at the keyboard and hammer away about the "disgust".
And also remember what is being discussed, as usual, are the isolated incidents.....the other 98% are doing just fine and normally not discussed.
Lastly get up quick and turn on the sprinkler system!
