A Vintage Shorts "Short Story Month" Selection   The ride to the tiny village in Mexico where he's due to film has not been easy. The actor has to first put up with Gunther, a maniac German driver in a tuxedo, the Narcos who insist on excavating the contents of their car, the customs official in Mexico who sends him back across the border, and an embittered woman in the Mexican consulate for whom he must play Spencer Tracy.   From the Pulitzer Prize-winner, "the greatest playwright of our generation," director, prose-stylist, musician, and actor Sam Shepard--"Spencer Tracy Is not Dead," selected from Cruising Paradise, is a gleaming testament to Shepard's mastery and a tender portrait of American masculinity on the road. An ebook short.
