I used to post those brightly colored "Beware of Dog" signs on my property even when I didn't have a dog. I see those types of signs as a fair warning to meter readers and a deterrent to ne'er-do-wells. My wife has never liked Beware of Dog signs because in her mind they look "tacky". To get past my wife's objections, I found a work around solution, and made a low key wooden sign that reads "There IS a Dog". Now my wife is happy, and the bad guys have been duly warned. Problem solved.
I would like to say a special "hello and thanks" to all my readers outside the United States. Glad to have you on board!
