UPDATE: This is the MPVA Carvan. Read more about it below.

A caravan of 50 or so old flatties (mostly military) with license plates from a variety of states was spotted heading down the new Legacy Highway (the new north/south alternative to I-15) in Utah yesterday.

A reader named George pointed me to the MPVA website to answer the questions of who, what, where and why.

From the MPVA Website, “As part of its mission to honor our country’s military vehicle history, the MVPA has decided to recreate the famous 1919 Convoy in 2009 as a 90th Anniversary celebration of the achievement and in conjunction with the nation’s President Lincoln Bicentennial celebration.

This is a Convoy of historic military vehicles – of all eras, from WWI through to current-issue military vehicles. The vehicle roster currently includes WWI “FWD” cargo trucks, through to Harley Davidson WLA motorcycles, staff cars and jeeps to later model M813 5-ton cargo trucks. ”

Learn more about this ongoing convey from the MPVA website.  The Convoy should be arriving in San Francisco on July 8th.
