Thought of additional stuff. You'll be most impressed with the exhaust note of the safety car...for that matter the medical MB sounds wondrous also. Take binoculars. A Sony walkman...yeah. The announcers broadcast over an FM station, the public address system can be problematic at times. Then there's the Parade of Nations...pretty Canadian flag girls march right by you. Then there's the driver's parade. It's done by transporting the drivers in sharp looking Austin Healey 100's, 100-6's, and 3000's. They'll stop right in front of you (GS12) with typically the front row drivers getting out for a surprisingly good interview.
and additionally,...Canadian Air Force pilots really know how to do a flyover. As they get to GS11 & 12, they go into a ridiculous climb. You'll approve.
