The Nebraska Traditional Archers club has an annual bow/arrow building workshop in the late spring/early summer in Fremont, NE. That would be about a 3 hour drive for you. We meet at a really cool facility (The Isaak Walton Cabin) and have a great time building, learning, shooting, etc. Here's a link to their page:
