Dan & I have both used Chipping Norton in the past, plenty of good opportunities there but morning or late arvo (sunsets are great) are the best times, there is also plenty of spots to get filtered light if the sun is a bit harsh
A couple of links to some pic's taken at Chipping Norton, the first lot were taken with my old point & shoot camera, the 2nd link is with my new Canon and I'm busting to get some more car practice with it.
