This is my favorite confusing area of Calgary:

You have 77th st running into 75th st and 73 st, and if you look for 74th st and 76th st, they are not next to them, they are south of Bowness road. Just stubs of streets.
Off the the SW you have 36th ave turning to 40th ave for 2 blocks, and a bunch of other weird stuff around. Go Bowness.
