Hypothetical: A weather event keeping bands from attending area that were originally going to attend is an apple to an orange here. What we have is schools (military) that have no intention of attending the area contest since they have their own state competition. The rest of the bands in Area C should have the same chance of advancement as all other areas in the state.

Area C qualifiers will be at the contest. The rest qualified for the military state contest.
Should the bands in area C be able to advance to state military contest because the earned a division 1 and "qualified" for that contest? The answer will be that they have to choose open or military, which further proves the point that it needs to change.
