start here:

http://www.williamsgrove.com/forum/viewforum.php?f=8
be sure to check all the links to the shooters sites.

then go here and scroll to "this weeks photos"
http://southjerseydirtracing.com/main.asp

the shot you are looking for is in one of those sites as well as a lot of other very good on and off track shots.
probably be more posted overnight since the grove rained out.
