Back when I lived in Vancouver (BC), there was an annual apple festivatal every fall in the UBC Botanical Gardens. You get to see and taste (!) several dozen of varieties and that was quite an experience. They also sold a dozen or so non-mainstream varieties at the exit, which too was an awesome thing to have. Highly recommended if you are in the area... though I must admit that apples are my all time favourite fruit, so there is a bit of bias.
