I was out that way a few weeks ago and there was an Appleseed event going on at the 100 yard range. Even with a group of 16-20 there was still a ton of room. Never had an issue with space there. It's truly an amazing facility.
I remember way back when I lived in California, I'd drive out to the range at 7am to get there before it opened. It would get so crowded that if you didn't get a lane at 8am, you'd have to wait until 10am when they'd kick people off. I don't miss that at all.
