North is up. x is real longitude and y is latitude, so the crossing still falls
out of where home sits — longitude is timezone, and New Orleans lands at
20.4%, within a point of the rank-derived 21.4%. Two latitude scales: ranked
spaces the cities evenly and keeps the north-to-south order, true uses honest
degrees and shows what that costs, since nine of fifteen cities sit between
28 and 41 degrees north. Events are invented; the roster is real.
