that place is a fuckin mess!
Yeah right, you should see the desert around Las Vegas. Sloan Pit (where I shoot) has so much garbage it's absolutely disgusting. I will take pictures next time I go out.
People never pick up what they bring with. Targets, brass/steel casings, shotgun shells, couches, televisions, paint cans, glass bottles, plates, wood pallets... you name it.
We have volunteers go out with a full construction sized dumpster every couple of months and even when it's full, it doesn't look like anything has been cleaned.
