Actually I must correct you, OC Parks is now part of Community Resources, no longer part of RDMD.
OC Parks Silver 1 is the old RDMD Silver 3 I guess for interop when needed. OC Parks Silver 2 and 3 are new talkgroups. All three are on the Countywide with roaming on Laguna Cell. They are now known as Station 92 and are dispatched by West-Comm (Seal Beach PD consolidated dispatch center) under contract.
