Strip Maps and the CAA / Triple-A

Westworld, the Alberta Motor Association's members' magazine, kindly took a short article of mine linking Ogilby's strip maps with those little route maps you can get as a CAA / AAA member. They've put it online: http://www.ama.ab.ca/cps/rde/xchg/ama/web/membership_AAY-Feb07-Main-Teaser-Page-7372.htm#Article7322  (Note: The map in the article is by Thomas Gardener, not by Ogilby. It follows many of his conventions.)

As usual, things cropped up which were cut. I discovered that strange family of measurements: furlongs, firkin, fortnights, and fathoms.1 There was also the obsolete origin of the word 'turnpike': "A n. I1 Hist. A spiked barrier fixed in or across a road or passage, as a defence against sudden attack. LME."2 I got the impression that this was also done to block optional routes, keeping traffic on the main roads.
