Is that what they turned Hunter Liggett into now? Last I was there, it was abandoned. I took an off-road group down to Big Sur one year, and we made our way over the mountains to Hunter Liggett. to my surprise and delight, and it was empty. The kiosks were tipped over and there was no one there. We off-roaded all over there in the fall, and never saw anyone. We used to also go there on the old Indians Road on our dirt bikes from Arroyo Seco in the 1970s. That is all closed off now on the Arroyo Seco side now though, with a campground and fee park.
Funny story: when I worked at General Dynamics in San Diego as an engineer, I passed a guy's cube one day and saw that he had a 3-dimentional stick figure mapping array on a monitor, and it looked like Arroyo Seco. I asked the guy working there if that was what it was, and he said yes. He showed me what he was doing, and we plotted a route using a light pen up into Hunter Liggett along the Arroyo Seco River for fun. I did not think anything of it until I passed that cube the next day and everything was gone! I found out that it was moved into a 'black' lab, a secure lab requiring higher security than I had. Evidently the guys manager had noticed my noticing the mapping scheme, and if someone passing by in the hall could recognize real features from a stick figure targeting system, it needed to be secured. That was a group developing programming tools for the Tomahawk cruise missile on battleships (early 1990s).
