I work just over in Clayton Park and was going to try to find somewhere to take in some of the show today, but as luck had it I got tied up and just saw the end of it streaming CBC.
I was down on Sunday and touried the USS Wasp, HMS Ark Royal (my grandfather sailed on WW2 Ark Royal, fortunately had been transferred just before it sunk), HDMS Ejnar Mikkelson (pretty neat little ship, actually), HMCS Toronto, and BNS Independencia. All interesting tours though you don't really get to see much. Ark Royal and Wasp definitely had the best organized tours, lots of displays to see and good crowd control. Overall my father and I had a great time, found most of the sailors (and Marines in the case of Wasp) to be great to talk to, all enjoying their time in Halifax.
Independencia was interesting, but it definitely was not set up for pleasure tours, and virtually none of the crew spoke English, fortunately my fast-fading Spanish and a smattering knowledge of Portuguese helped.
I'm going back tomorrow to see HDMS Absalon and whatever else I can get aboard.
