Thanksgiving, Halloween, Christmas in that order. An 'Attitude of Gratitude' is a foundational principle of my life. Halloween's ok. Christmas has been destroyed by the commercializers and the religious bigots. I'd rather face a firing squad than Christmas. Bah, humbug!
Halloween is the most fun, its the one time of year when dressing absolutely ridiculous is socially acceptable. Plus you get free candy. Christmas is to calm and long, thanksgiving is just a bunch of food then its over. you can use your imagination and creativity for halloween.
