In spite of efforts to bury it, Halloween has grown into a commercial holiday second only to Christmas. Still, All Hallow's Eve in the face of the 'Tis the Season retail monster can't slow that Christmas Express. Who knows? Perhaps, the Fourth of July is the next holiday to fall in the face of the Christmas avalanche. There are, and have been for some time, a smattering of year-round Christmas shops, but those rare operations are different types of intrusions on our sensibilities. The Christmas season foisted upon us by big retailers since early September is a full frontal assault on the more traditional view of the holiday season.
