I'd maybe lean towards Sunday as the better day (just slightly!) as you may see people trying to go for the win and such. Two day event, best time from each day adds up to your total time and is used for position.
This waypoint is the entrance to the site. Follow the signs once you gain entry and please watch your speed. No wondering off the route to the site will be tollerated and could jepordize our use of the site. Spectating should be great both days but CP is always fun to watch. They run Heat 2 which I would expect to start around 10:30 and end at 12:00 Saturday, one hour earlier Sunday
