Randall Holden comments on the rockers:"I believe the 75% rocker represents the participation rate of troop membership at summer camp."
Can anyone add to this? There does not appear to be anything on the web about this rocker. This seems to be a fairly limited set of rockers from KMSR. Do you have any that could be added?
