...and my friends who are coming with me are interested in the Normandy beaches and battle sites of the WW2 Canadian forces, so we will be doing those.
Don't forget to remind them that Canadian forces played an important role in the Italian campaigns from Operation Husky, to Monte Cassino, to help liberate Rome, to all the way up to the Gothic Line in northern Italy. This might spark an interest to go to Italy (hint, hint). Oh, and did I mention that the tank museum (Museo Storico della Motorizzazione Militare) in Rome has a lot of tanks?
Side Note:If you and your friends also like aircraft, and you are in Rome, then you have to visit the Italian Airforce Museum (Museo Storico Aeronautica Militare) which is just north-west of Rome located at the picturesque Lake Bracciano.
