Wow! Lucky guy!
When I lived in Southern California, I was a member of a club that leased range space in a National Forest, from the US Forest Service. It was an improved range, with a 1,050-yard rifle facility with a covered firing point at 600 yards, a covered NRA-style pistol range for 25 and 50 yards, shootable open woodland, and a "freestyle" pistol range with a Cooper Wall, a Jungle Walk, barricades, and well-marked distance lines from seven through 75 yards.
Although it sounds like paradise, it was 60 miles (about an hour and a half) away, so it mostly got used on weekends. But I used it at least once a week, to both learn and maintain my skills. When I was still shooting competitively, and a match was coming up, I was there on both Saturday and Sunday.
That range is the only thing I miss about Southern California.
Of course, nowadays Jean and I shoot on a friend's land, less than 15 minutes away. But it's just woods with a safe backstop, and it's for pistol distances only.
