There really wasn't any signage around for spectators, so when we caught up with a heap of cars travelling in convoy we, and quite a few others followed the convoy.
This turned out to be officials cars and when they turned off to go to the start line though a closed road many of the spectators followed.
Thankfully we had the UHF scanning and spoke to the officials before following them, but apparently there was a lot of spectators trying to turn around and having no idea where to go.
