Does anyone know what exactly 852.5375 167.9 PL is used for in the Inland Empire? I just heard a pursuit here with street locations in Moreno Valley (Riverside County). The database shows it as Chino Hills State Park, but I think this is unrelated. The units were definitely State Parks (SURCOM dispatcher callsign), but I am just trying to figure out exactly what area this freq covers. Perhaps another freq for Lake Perris?
