DJ,
If anyone gets out for a road trip this summer here in the states, you might want to check out this Museum, The Heartland Military Museum, Lexington, NE, Exit 237, I-80.
I've personally driven by the place but I've never been able to stop and check it out.
You can see it from the Highway and they have a M4A3E8 out front along with other equipment, Helo's, Jeeps, M4 Fast Tractor, Bradley, M113, and one of the first military tractors. They have a Website too, no photos of whats on site I'm afraid.
Next time I'm thru that area I'll see if I can't stop and snap some pix for you all.
