Been a few years since I went to any show but didn't the parade laps happen around dinner time?
Might just be an idea if you don't want to watch to go chow down on some lunch.

However, always has been and always will be tossers that hang back and floor it, like we've never seen an RS at full tilt before, gives drivers that wouldn't normally venture onto the tracks a sight of them and a small taste of how the shiny shed they are driving should be driven should the moisturiser and cloths ever leave their hands, in short dull and boring like a night on the rsoc forum
