That ACO roof terrace did look good. You'd get a shot of the cars coming towards you through Corvette corner. The karting pits are a good place to watch the action but from a photography standpoint, due to the catch fence, you can only really get the cars going away from you and towards the kink. In a giant tarmac expanse. So it depends how you define a 'good' photo.
Can't be long until those karting pits get torn down by the way.
Those bar structures are well worth buying a beer and going in.
