A couple weeks ago I was able to get to the Patton Museum's 60th Anniversary event. This included quite a few display vehicles and a mock battle. I have updated and posted a bunch of photos to my Picasa account, at:
The new albums are "Sherman Types at the Patton Museum", "German Equipment at the Patton Museum" and "GB at the Patton Museum" 9which includes both of the previous but hasn't had the captions added yet). The main file has 370 photos, so it might be a pain for dial-up users.
