My dream would be to visit all these tank museums:
Kubinka Tank Museum — Russian Tank Museum
Musée des Blindés — French Tank Museum
Deutsches Panzermuseum — German Tank Museum
Patton Museum of Cavalry and Armor — United States Tank Museum
Yad La-Shiryon - Israeli Tank Museum
and the U.S. Army Ordnance Museum at the Aberdeen Proving Ground, in Aberdeen, Maryland, USA.
I have visited the one at Bovington thrice and it was wondrous. My next plan would be to visit the French Tank Museum at Saumur.
