"In 2015, while, in his words, "dismantling my house in New Jersey and preparing it for sale," Ed Roberson discovered in some envelopes in his attic a manuscript he thought lost, drawn from the experiences of the summer of 1970, when the poet, along with two friends, rode cross-country from Pittsburgh to San Francisco and back on two BMW motorcycles. The recovery of this manuscript--over forty years later--alerted Roberson to the fact that he had been relating to its material ever since, yielding for him work that "calls across the span of a lifetime." MPH is Roberson's epic, serial road poem, decades in the making, stamped with and guided by the talisman of its title"--from back cover.
