Top off (or kick off!) your Downtown Trick or Treating evening with a trip to the Haunted Museum inside the Great Lakes Maritime Heritage Center.  This is an all ages, free event. There is trick or treating, games and the ghost ship is optional.  This event is possible because of support from Friends of Thunder Bay National Marine Sanctuary, many candy donations, and lots of volunteers.  The Haunted Museum coincides with Downtown Alpena Trick or Treating and generally happens on the Friday before Halloween.
