I was privileged, recently, to be able to go to a private tank collection in Los Gatos, CA. It was a once-in-a-lifetime opportunity to be able to see, climb on, and get into actual combat tanks from over the past 75 years. It was truly amazing. My friend Landon and I had a personal, private tour from the Military Vehicle Technology Foundation. See for yourself.
Oh, and by the way, most of these tanks are fully operational.
