Bay seniors, despite lingering pacifist sentiments, might appreciate modest displays of military might in local July Fourth celebrations. In Novato parade organizers traditionally include tanks from the WW II US Military Museum in San Rafael. The collection there spans 65 vehicles including a gun motor carriage as well as historic bunkers, uniforms and equipment. No phone or email available so I can’t tell you the hours or the admission. A vaster collection, in fact the largest private one, is at the Military Vehicle Technology Foundation down the Peninsula where group tours are available starting at $500.
