We weren't lucky enough to have these four visit our house last Wednesday, but you may have been. These wonderful young people are our four grandchildren, and they are, of course, dressed for an evening of trick or treat. The Queen of Hearts is Savannah (11). She is clearly a heart breaker. Next to her is Ian (8) dressed as Luigi, a character in a Mario Brothers video game. The Green Power Ranger is Jackson (5), and Buzz Lightyear is John Michael (2½).
