A-This is a pretty complicated question but here goes:
From West of the track (or the airport for a landmark), get to 71 somehow (south on 183 or east on 290) and travel East on 71. The airport will be on the right. Once you pass the airport you're going to want to turn right onto 973 (it will be at a gas station). Go down 973 until you cross a river and then turn left onto Pearce Lane. Now go down Pearce past all the housing developments and the track will be on your left, near the top of a hill.
From East of the track, get to 71 and go West. Turn left at Ross Rd And then turn left again onto Pearce. If you miss Ross Road you can either turn around or just go on down to 973 and turn left there.
