Howdy and welcome to the forum. I loved Garfield as a kid and definitely can still relate to him. I say your'e never to old to trick or treat (as long as you're dressed for the occasion and you give as good as you get). Happy haunting!
Warm Welcomes! I absolutely love your screen name, that Halloween special was always one of my favorites and I finally bought in on DVD last year. That's one of my favorite parts, too. Gar-Halloween-field. So perfect!
