The world is not a perfect place. Because it's not, perishable skills need to be renewed. Southern California is a place where the Mojave Desert meets the ocean.
There is only green grass because water is pumped in from the Colorado River and from Northern California. Thus, it's not a long drive from that beach environment, teeming with people, to places such as that shown (above and below), where you can go and be unmolested while you train. The dry lakebed (above) is located between Barstow and Baker, CA -- some distance to the south of both of those cities.
My youngest daughter wanted to get some trigger time by going in the Mojave Desert so we drove out to hone some of her skill sets. Pictured - E. L. shooting a Glock Model 21 (modified).
There are two sorts of people in the world: trained an untrained. Meeting threats requires that you engage different targets at different ranges. In this case, from ten meters to twenty-five meters. Each target had a "same threat level" criteria, however both speed and accuracy was stressed with focus on shifting targets for double-tap and re-engage. You will also notice that there is a "gingerbread man" Christmas yard "ornament of sorts" in the foreground. High expansion .45 ACP +P+ rounds left .07 inch holes in the plywood (most satisfying).
In a complicated world. Preparation removes doubt and concern.
