City squares to island causeways to the port gates — one line covers the whole map, around the clock.
Downtown, midtown, the Southside — the home map.
The boomtown west — I-95 exit 104, Tanger traffic and all.
Port country: truck routes, early shifts, Highway 21.
The Southside's far edge, where response times usually die.
The islands, the causeways, and everything past the Bull River bridge.
North gate of the port, I-95 exit 109 corridor.
