the folks at Road Runner magazine ( to which I subscribe, and which in every issue offers up intriguing ride information - unfortunately usually in too-distant places!) have put together a series of motorcycling route maps, each covering a state or small group thereof, mostly out east. $9.95 is cheap, but it also seems there are only a half-dozen to a dozen trips highlighted, so whether this is good value or not is debatable. however, all info is good info in my view, and it's nice to have ares covered that aren't in the Destination Highways or Butler maps regions.
strictly fyi, I've not seen even a single example, so no comment on quality / content.
