A country Christmas isn't exactly at the top of Emma Townsend's "Dear Santa" list this year. Flannels and work boots? No, thanks. She's a dignified Manhattanite now. So how did she end up back in the "winter wonderland" yet again? It's family tradition, and she can't let her parents down. This is it, though -- this is the last year she forsakes her life (and fashion) for ornaments and tree trimming and live-action nativity scenes. No matter how good-looking that guy in her parents' yard is. Wait, where'd he come from?
