I went to the Colling's Foundation WW2 reenactment in October in Hudson, MA. Huge collection of tanks, equipment and weapons. All of the equipment worked, everyone was shooting blanks even the cannons. I brought my Canon 7D and 70-200 F4L. I will definitely be going back next year. BTW the old guy on the M2 on the Sherman had the biggest grin I've ever seen.
