I would bet this:
sectional 1: Crown Point, Lake Central, Merrillville, Hammond Central
Sectional 2: Chesterton, Elkhart, Penn, Portage
Sectional 3: FW Carroll, Homestead, Warsaw, Lafayette Jeff (Jeff is a tricky one to position)
Sectional 4: Noblesville, Westfield, HSE, Fishers
Sectional 5: Pike, Zionsville, Brownsburg, Avon
Sectional 6: Ben Davis, Perry Meridian, Southport, Tech
Sectional 7: Carmel, North Central, Lawrence North, Lawrence Central
Sectional 8: Warren central, Franklin Central, Center Grove, Columbus North
