If you have any districts that applies to the whole county, you dont need to open those ie Flagler County has 1 Congressional so I really dont need to have that district open.

    All districts are visible but unselectable

    *All are opened and ready to get the New Redistrict Window**You can see the red and white of the SB and also CDD blue and white.By putting the larger weight line behind the color it shows up a little better

    *Set it up to your preference**We are going to combine precinct 11 into precinct 2As you select the blocks, you can see the on-the-fly (visual what if) your block count and population will decrease in the precinct that you are getting rid of and increase in the precinct that is gaining those blocks**
