I too recall going caroling with my mother and siblings when I was younger. One year, my mother insisted I bring my trumpet and play instead of sing, as she thought it would be more festive. In retrospect, while I didn't really enjoy it at the time, I regret not taking advantage of the time with my family; I think I'd probably enjoy it a lot more today.
Christmas in Los Angeles is odd. We have our tropic/desert weather and architecture and greenery, plus the holiday decorations in the sunny warmth most of the time. For an East Coast transplant, it took a while for it to really stop being unusual to me. But I have seen and heard carolers since moving here, and certainly there are groups doing it back home in Virginia and DC.
YMMV of course.
