I am also one who loves the traditions and mythologies behind the holidays. That any of the old ways have survived to be part of this holiday, or any other holiday is amazing to me.
So light the Jack-o-lanterns, let the little ones dress up and trick-or-treat (don't forget to say thank you!), enjoy the turning of the season as the days are becoming shorter, nights longer.
The comfort of the cycle of days and years continues; fall to winter, spring to summer. Enjoy.
