I love history. I think that it is fascinating to learn how we got were we are today. I went to this (as well as the slightly smaller "Blast From the Past" at Broadlands) http://www.english-heritage.org.uk/daysout/events/festival-of-history-2010/ earlier in the year. Its a fantastic way to get kids in particular, interested in history. It`s very "hands on", unlike book learning, and also very informative, not just the military stuff, but the Living History groups too.
