Just another heads up that the military museum in Oshawa has a super event next weekend 27-29 May, if you are in the area its worth going to so you see things exploding, tanks shooting (blanks), reenactors and vintage equipment, scale model builders, militaria and milveh parts venders....much to see and take in.
