Drummond cemetery is where the war of lundys lane occurred in 1812 in which many soldiers lost their lives. Laura Secord delivered a note to warn the soldiers of a coming attack. The cemetery is most def haunted. Not ideal for an investigation
Reverent Acres Farm in Charlottesville, Indiana. Really cheap for an overnight stay. $25 per person with a minimum of four. They don't have beds though. http://www.revenantacres.com/calendar--rates.html
