Well out here in the desert, absent of any rain, we don't have any grass, but a lot of mesquite brush, which is really easy to clear out prior to shooting. So then you've got a whole lot of light brown dirt to retrieve your empties, provided you've cleaned them up prior to shooting them. Don't ever think I clean my brass casings to make 'em look pretty, it is because they shine. You can't believe the number of older abandoned casings, I find while retrieving my nice and shiny brass.
