Volunteers Here you can sign up to help out at Tinnfest! September 8,9 & 10 We need volunteers to work in the beer garden and the concessions booth. By staffing these positions, Youth Ops will receive a portion of the proceeds. (You must be 21 or older to work in the beer garden) Multiple volunteers are needed during each shift. As long as there is a “sign up” available for a particular shift, volunteers are still needed. Thanks for your support! If you have any questions, please email Jenifer Priest!
