My experience has been similar to restrac's. First trip was in '06 with a bunch of experienced GC runners. Ranger Dave seem fine with us. No weird new rules. Now, in '09, even though it was late in the afternoon and the commercials were finished with their rigging, he did get a case of the ass because we had more than two vehicles down at the ramp and wanted to do the gear inspection right then and there even though we weren't ready. Last year was pretty normal as well. Very thorough. The ranger wanted to actually see the fire pan, not just see the bag it was in even though it seemed pretty obvious to us what the shape was and it sure sounded like steel when we tapped on it. They probably have good days and bad days like anyone else.
If I remember, I'll post about our experience after our Sept. trip.
