I looked back at the discussion and here is how I'd divide the races. SEK stands alone, clearly, and the rest are separated by population. I felt it was important to separate suburbs from stand-alone towns, and I added Haysville because I felt south Wichita suburbs were underrepresented. The order within each division is my personal rankings; where my experience was limited I went with the most persuasive board opinion.
