thanks joe. that is the section i remembered but couldn't find in my quick flip through the gcr this morning. the sfr "shall" provide for ITR. even if they run restricted regionals, they still have to provide a race for ITR.

in the wdcr case, the classes in question were national classes and the wdcr holds separate races for national classes, so this "shall" requirement would have been met if we went to restricted regional without the national open wheel classes. not the case for sfr since itr can't run in a national race.
