A group of 54 13-year-olds spent the weekend learning to navigate activities such as wall climbing, rappelling and obstacle courses in an environment of military discipline designed to help build a foundation for the teens as they face difficult life choices in the coming years. Gut Check 2017 was held Thursday through Sunday at Riverside Military Academy. The program, sponsored by the Gainesville Jaycees for the past 20 years, had been at the University of North Georgia’s Dahlonega campus until this year, according to Cory Cummings, a member of the Jaycees and executive officer for Gut Check for the last two years.
