Call it TART, for short, but don’t confuse Two American Road Trips with any stinking Big Government rescue scheme.

TART is the unofficial acronym of “Two authors, two road trips, two Americas,” a co-venture in travel book promoting and selling that’s being put together by me and my new pal Ethan Casey of Seattle.

Ethan — billed as a liberal and author of “Home Free” — and I — billed as a true-blue libertarian — are going to hit the highway this fall and appear together at libraries and indy bookstores from coast-to-coast.

We’ll each spew our versions of the America we saw from the front seats of our cars. Ethan out-drove me, wracking up 18,000 miles in the fall of 2012 to my puny 11,276.

So far we’re only officially booked into venues in Seattle and Mt. Lebanon, a Pittsburgh suburb.

But more dates are going to come, especially in the Bay Area and Monterey County, aka Steinbeck Country, during late October and early November.

Anyone finding this page knows the pain I’ve caused Steinbeck fans. But here’s a little blurb from the PR department about young Mr. Casey:

In the fall of 2012 Ethan Casey drove clockwise around America during the election season.

The result is “Home Free,” an entertaining and edifying work of personal reporting in the spirit of his previous travel narratives, “Alive and Well in Pakistan” (“Intelligent and compelling” – Mohsin Hamid) and “Bearing the Bruise: A Life Graced by Haiti” (“Heartfelt” – Paul Farmer).

“I’m now turning my attention to another society struggling through a time of confusion, economic and political distress and transition,” says Casey, who’s working hard to finish “Home Free” by fall. “America is susceptible to the same forces and trends as any other country.”
