Jeremy - I get it, grew up out there in the sticks. I would think Hays High or even Russell both of which have 2 gyms might be able to host it. Packed full sure but not crossing 3/4 of the state to get there.
The numbers are a bit confusing however. Here are the changes with the new boundaries:
D1 -11
D2 +15
D3 -17
D4 +13
I only checked the mileage in D4 because lets be honest all others are close. 101 miles was added to the North part and 33 less miles in the south.
And you could be right about reaching Topeka soon. Johnson County, Wyandotte (KC) and Douglas (Lawrence) are projected to have the most growth over the next few years (84% of the states growth). Riley and Sedgwick are the other two in the top 5 growth. Dodge City is the only real Rural area with growth projections.
