Tony, there's some weird sh*t goes down in MB. Take your pi-meter with you, and try and stay in the more stable areas. And keep away from the Smokie zone, last time I walked past there it sounded like a cross between a sawmill and a slaughterhouse, and that was only about one in the afternoon.
By Wednesday lunchtime you should still have a decent choice of spots. Our intrepid lads who were slingshotting round the Kuyper belt have sent back a couple of early photos, and I've posted one below. It's early days in their journey yet, but you can see that there's still quite a choice of pitches.
