The link below will take you to a site where you will find the book
Across America by Motor-Cycle.
The book is written by CK Sheppard who travelled from Britain to Canada then on to New York where he bought a brand new 1919 Henderson motorcycle in order to travel across the country to San Francisco.
CK has a unique writing style and you might find that his description of early Americans is very similar to the present day version.

On the website under the news tab you will find some videos of his bike and the journey.
