I strongly recommend never driving from Saskatoon to Winnipeg ever in your life. It was so, so, so boring. Fly if you have to, just don’t drive!
We spent only one day in Winnipeg, and visited Landmark on our way East. We realized that, between the two of us, we probably have more friends in Winnipeg than we do Edmonton!
We visited the Saint Boniface Cathedral, which is really only an empty shell. The church burned down in 1968 and only a few walls remained.
