The first Clocktoberfest occurred in 2007, as a campout and exploring meetup for Iowa and Minnesota urban explorers. Over the years, this annual event has expanded and become a traditional institution for Midwest urban explorers. Through the communal aspect of this meetup, familial bonds have been built linking the Twin Cities urban exploration community with exploring communities in Kansas City, Madison, Appleton, Chicago, Rockford, and many other Midwestern strongholds. This year was the first time Cincinnati explorers joined in the festivities. Activities this year included Union Park ruins and cave, a large group rafting excursion to "Floaty Boaty" mine, smaller group exploration trips to abandoned power plants and breweries nearby, and of course the traditional Pits Cave.
