On March 7, 1905, a group of little more than 60 people gathered in the Granger Meeting House for the weekly meeting of the Mutual Improvement Association. No one in attendance could have predicted that the night would end in disaster, with what would become known as the Granger Meeting House Explosion. The meeting was called to order at 8:00 p.m. sharp, and following the opening prayer, a 21-year-old woman named Nellie Mackay walked up to take her place next to the organ and sing for the audience.
