Neat! I've got a slice that's under 10 miles long going south into town, but I've also got 14 slices to the north (the ones that don't intersect with a couple up-state cities) that are over 3000 miles long.

Vancouver is similarly interesting, a lot of great-circle 2000+ mile segments that reach over towards New England, but everything west or north is invalid.

Would be neat if instead of a single yellow petal to 100k, each petal was a color gradient to 1k, 2k, 10k, 20k, 100k, 200k, or 1M people!
