I'm lucky that all of my gun club's ranges are wide, flat bare dirt areas, several separate pistol and rifle ranges. They keep it scraped with a tractor and blade too, and spray the weeds they can't scrape off.
It's pretty easy to find my brass, and lots of extras that others seem to "forget". And the wind and rain always seem to uncover lots of old brass.
Since each range is essentially private because there's plenty of them and no need to "share", there's no question that you can have what you find. Ain't nobody else there.
I think there's a dozen like this one, from 25 to 100 yards, some narrow, some really wide for events/multiple shooters. Private club, very remote, usually pretty quiet and dead during the week. You can drive right down to the impact areas and setup/teardown/cleanup your targets and stands, and you can put the benches anywhere you want. I usually setup right near the left corner of my tailgate, and the brass plops down around the bench. I have access to ALL of the crap that I drag with me, I even bought a screened picnic tent thingie for shade in the summer.
