The Reading Air Field is not quite a full-time military installation, but during a special weekend each summer it becomes a WW-II battleground, with US, Canadian, British, Nazi, Japanese, Australian, and all sorts of other camps, aircraft, mock battles, flights, etc. The WW-II weekend has been a highlight for us each summer - see http://www.maam.org/wwii/ww2_sched.htm for details!!
