Halloween has arrived, and it's often heralded as the start of the "Holiday Season." That being said, I'm curious; what is your favorite Halloween - or other Holdiay Season themed - adventure?
(I'm suspecting a lot of Ravenloft

For me, it's the old Judge's Guild adventure, "House on Hangman's Hill." Ran it this past weekend with the family. Four characters (fighter, wizard, cleric, and ranger), 5th level, with two 3rd level fighters as henchmen. They made it pretty far, but ran afoul of the spectral skeleton (that they should have avoided). Overall, it was a good time.
Anyone else have a favorite holiday adventure?
