Large uncertainties remain in our picture of the evolution of stellar rotation and activity in Sun-like stars after they reach the age of the Hyades, roughly 0.5 Gyr. Rotation periods are scarce for stars at these ages, seriously complicating the calibration of an age-rotation-activity relation that could be applied to field stars. The Columbia/Cornell/Caltech Palomar Transient Factory (CCCP) survey of open clusters is an effort to systematically map stellar rotation in nearby open clusters. We present preliminary results from our on-going CCCP campaign on NGC 752, a 1 Gyr open cluster for which we have several hundred individual R-band observations. At a distance of only 450 parsecs, and with deep archival X-ray observations, it represents the best opportunity we have to study the age-rotation-activity relation in main sequence stars at an age about a quarter that of the Sun.
