From the quick look I had, the Occupy Calgary at Olympic Plaza did pretty well. I didn't see any obvious damage from the wind. The tents, as you can see, are standing. Although, I'm sure they must have some difficulties. I did have a slightly unpleasant circumstance, since one lady was complaining about pictures being taken by me. She didn't bother saying anything to me directly, and another person said people are free to take pictures. No big deal. Just a bit annoying, when people demonstrate in public to get attention, but don't like the attention (again, this was just one person, so nothing relevant to the group as a whole).
This is Jasleen at one of the campsight shelters. I liked how her coat looked like it was blowing in the wind (even though I don't think it was).
