Last years master state bracket looked like this:

District 1 - First
District 2 - Fourth

District 4 - Second
District 3 - Third

District 4 - Third
District 3 - Second

District 1 - Fourth
District 2 - First

District 3 - First
District 4 - Fourth

District 2 - Second
District 1 - Third

District 2 - Third
District 1 - Second

District 3 - Fourth
District 4 - First

So it appears that this year's bracket would be as follows:

District 1 - First
District 3 - Fourth

District 4 - Second
District 2 - Third

District 4 - Third
District 2 - Second

District 1 - Fourth
District 3 - First

District 2 - First
District 4 - Fourth

District 3 - Second
District 1 - Third

District 3 - Third
District 1 - Second

District 2 - Fourth
District 4 - First

It could be that the seconds and thirds are reversed within the brackets, however, I'm not certain. Maybe, Mike can confirm or correct this.
