I lived on Treasure Island (where they sometimes film) until they decommissioned it and we moved to the Coast Guard housing right outside the Alameda Naval Station (where they use the runways).
I really miss living there but it was so expensive. On my last trip out there for work I went by M5 but they were filming inside and had signs on the door that said don't knock. I stuck around for a while hoping to catch a glimpse of Kari, I mean any of them
but no one ever came out..
