If you're looking for some cheap motorsport options post Nationals, the next multiclub hillclimb at Dapto is June 19. Regs and entry forms are available from http://wscc.org.au/download.shtml 

Entry fee is $90 up until the Driday before. You'll have already covered the other expenses at Wakefield. If you're not familiar with hillclimbing and Huntley, its a single car time trial event over a 700ish metre course. Couple of flat out sweepers, a series of esses, and 3 flat out sprints along the straights. A bit like a mini tarmac rally you could say. The classes are the same as the supersprint (unless you have modified 4wd turbo). PM or contact me through the above website for more info.

ill be there to watch
