This is largely the history of the Lincoln Highway itself, its promoters, and its transportation context. The New York to San Francisco high way dates primitively from 1913, finally became an improved highway in the early 1930s, and ultimately declined as U.S. 50 and especially I-80 more effectively overtook its function. In addition to too much detail about the Lincoln Highway Association, there are many asides on transportation and communication in general, the auto and tire business, etc. This is not an exciting trip for those already aware of these well-traveled subjects.
