Boy Scouts Troop 45 will be at the event directing traffic and handing out the souvenir booklet to visitors. The troop will also stay overnight to help with security.
Scoutmaster David Getman said that between four and five adults and about 20 Boy Scouts participate.
"It's a night out where we get to actually camp with electricity, that's a rarity for us," Getman said. "The scouts have a good time assisting the church and they get to meet people and kind of show off our gratitude for the church. It's just one of those things that we like to do and we feel is our duty to do every year."
Getman said the church provides meeting and storage space for the Troup.
Four local churches combined to found the church in 1957.
West Crescent, Grooms, Newtown, and Crescent Methodist all contributed to the $2,000 purchase of land and went on to raise more than $40,000 for the initial construction of the church.
"How many struggling churches got together and gave up their identity to build one big church?" Predel said. "This doesn't happen very often."
She also said that added motivation for her this year was the recent passing of parishioner Martha Lane, who died earlier this year at age 103. Lane came up with the idea for the fair 50 years ago, and still made blueberry muffins for the church well into her 80s.
"That's one of the reasons I went back onto it, and getting a lot of our young parishioners involved in it that hadn't been involved before," Predel said. "I've been very excited about it."
