NORTH PORT, Fla.- This is a sure "sign" of true love.    

One very appreciative son put up this billboard to celebrate his parents' 65th wedding anniversary.

You can't miss it on US 41 at Toledo Blade Boulevard. It says, "Congratulations Roman and Orysia from your four truly blessed children and their families."
