Hypothetically - if you were going to blow up the calendar and you could work around athletics in South East Texas where summers are the surface of the sun I would love to have August through October off when it's actually pleasant weather and let's go to school November through July when it sucks. Spring break the first two weeks of April. Could still play football in November, December with playoffs in January. BB could be January through April like colleges. It could actually work.
We'd find out how many kids can actually learn if they had to start Region without masterclasses and then only had a month with directors to force-feed it to them and auditions could actually stay the same with S/E in March, UIL in June.
