Using Indiana as a Petri Dish and state population sizes aside. Lets use my county Allen (Population 385K). We have 4 school districs that include about 100K students (No mask mandate in any school since school began 8/15/21 )Avg. class size of 32 students. Now with that many kids going to class in and out of cafeterias, sporting events etc. not one school has been forced to close due to COVID outbreaks.
I know we are just crazy red state mouth breathers over here but just stating facts.
