The companion to “Mile Marker” is an old-school gas-station-style, difficult-to-refold-properly, Field Notes National Highway Map.
The map unfolds to 36" x 24.5" and features a large, colorful diagram of the continental Interstate System, designed exclusively for Field Notes by Mr. Cameron Booth of Portland, Oregon. It’s a beautiful and thoughtful data design solution.
The reverse side of the map is completely jammed with useful, sorta useful, and some fun-but-not-at-all-useful information. While it might not replace a GPS system for wayfinding, it is guaranteed to educate and/or confuse you during your next big road trip.
