AMERICA Ground Day could be organised more like the pirate day. You could get people to dress up as cowboys.
This would make it more fun as everyone would feel a part of the event.
You could also invite line dancing clubs (maybe a record attempt for the longest line dance in length?).
Country and Western bands and maybe invite American car, bike and hot rod clubs to put on displays near the town centre end, with trophies for the best. American Lindy Hop dance displays, American wartime vehicles display. You could invite western clubs to put on displays (The Remuda western club is only up the road in Kent).
This event could be so much bigger and better than it is at the moment. It just needs some vision and organisation.
