Well you are in luck based on where you live but some are little more than 6 weeks out.
Cloverdale, IN is June 12-14 I believe and Compton Rendezvous is June 19-21 in Berrien Springs, MI. Compton is a must for me!
Also look up the shoot in Farmland, IN south of you and the Ohio Classic (not sure on exact name, not been there). IBO is in Tenessee later this summer too. Can find all online or in Events and Gatherings Forum here.
You just missed the Kentucky TradFest last weekend in Harrodsburg which was great. Met several guys from IN Traditional Bowhunters Assoc. in Scottsburg and they have many 3D shoots all year.
