Go on SCRA Fan,on the main page there's a column on the right side that has message board and other features click on links,on that page scroll down to photographers and it has numerous listings of different photgraphers and their contact info.Other guys that I know that take pictures at Perris are Doug Allen;Mike Arthur,Stan Junior and Steve Lafond,so you might want to check with them as well.
Hope this helps you in your search.
Steve Lafond's info is under Tear Off Heaven Foto's
