Glad to hear I'm not alone in having been disappointed by the book...Perhaps we all have a propensity to leap at anything that touches on FFs and miles! I guess all the buildup, both here on FT and in the N.Y. Times Book Review, where Christopher Buckley compared Kirn to (IIRC) Jay McInerney in a gushing review, raised my expectations a little too high.
It certainly didn't meet them, although it was a pleasant enough little read.
