IIRC Ness ave. are the only ones open, meaning you'll be in "Sunny" St. James, a few blocks away from where I am typing from. The schools around here are great, and many have been recently overhauled. We got more culture then you can shake a stick at. Between the Winnipeg Symphony Orchestra, Royal Winnipeg Ballet, and a dozen or so Theatre companies; there be plenty for the kids and womenfolk to do. There's also 2 Major cultural festivals every year if your into the diversity thing. (Festival du Voyageur, Folklorama). Theres pretty much something for everyone here, as I think someone mentioned earlier.
If you haven't seen already,
