I remember one time getting an "obstructed view" seat in Northlands, the Oilers old arena. It was a single seat - you had the aisle on one side, and a giant support girder on the other. In order to properly see the ice you couldn't sit up straight, but you had to lean maybe 6 inches to the side to look around the girder. And of course you weren't sitting beside anyone.
That place really was kind of a dump.
