SWPI volunteers to host Public and Private ghost hunts at The Old Mill Museum in Dundee Michigan. We do this to raise money for the museum. The regular investigations run from 8pm-4am, the cost of investigations is $37, Old Mill Lock-In events run 8pm to 10am for $50, which includes your ticket to investigate, as well as a late snack/light meal, which will be served sometime around midnight. The Lock-In allows you to sleep inside the museum.
