Every year there is an annual "Jeep Festival" in held in Butler Pa to honor the birthplace of the Jeep. In 2011 they broke the Genius world record for the largest Jeep parade ever held with 1100 Jeeps. Next year is the 75th anniversary of the Jeep and they are trying to break the record again by attempting to have 2500 Jeeps attend. This is a large 3 day event (if my memory is correct) and Jeeps come from all over the USA. If you want to be part of the world record more information can be obtained on their web site. www.bantamjeepfestival.com
I have no connection to the event other then Butler PA is my home town and I saw an article in the newspaper.
I know several Model T fellows have Jeeps
Someone close to Fort Eustis, VA, should go there, to the Army Transportation Museum and see if they would consider taking their Bantam Jeep to the Parade. Having a lot of advance notice, might convince them to attend.
