Hi Nathan, I wonder whether the incredibly banked bends at Hamilton could prove a problem for a heavy vehicle like the mobile - there has got to be a lot of gravitational force pulling them down the track and if the surface is slippery they might have a problem. I doubt the mobile vehicle is 4w drive either. It would have to be the bends as I am sure any street car could drive up the straights after so little rain. Only thing I can think of when Hamilton has only had 3/4" of rain for the month (unless the track has had more than the weather station)
