There are no 6As without turf. FW Carroll was the last one.
As mentioned Castle, Mishawaka, FW NS, Concord, and the two TH HS in 5A don't have turf.
I also have Cathedral and FW Snider as the schools in these classes that don't have their own field. I did a breakdown off all the teams with turf and have kept that graph for about 4 years now and have updated it. When they come out with the new sectionals I will update it and check again. We are nearing 50% of the state as having turf.
