MERRILL - The historical society has been working on planning the event since last October.
A transportation theme was chosen for 2015.
"[We're] on our history hunt, and we are learning about where the railroads went around Merrill, how the river was important, where the trolley went, where the old highways go, and all of those thing are included in our packet of navigation," said Merrill Historical Society's Jane Francoeur.
Organizers say the event was a mix between a scavenger hunt and a trivia contest.
There were four different travel loops that went about fifty miles around Merrill.
Some groups that participated dressed up in team gear.
"[We're] trying to get out in the community, it's a neat place to live, and there's so much stuff that no one's ever even thought about. A lot of history," said event participant Sally Woller.
Five local judges will judge the best team name, costume, vehicle and the best selfie of the day.
