Been shooting there since the early 1990s. The conditions fluctuate. Sometimes it looks pretty nice and sometimes I haul out a whole truckload of garbage.
Still, it's free and pretty close to Hattiesburg, so I used it a lot when I still lived in the area. I miss it a lot. I also miss the little "gravel pit range" that used to be right beside the Longleaf Trace in Epley. That's where my avatar pic was taken.
The ranges in the Dallas area are nicer by an order of magnitude, but they're insanely expensive to use, and literally covered in fees, rules, prohibitions, surcharges, taxes and endless horse shit that basically sucks all the fun out of shooting.
Be thankful y'all have public ranges to use at all. Everything is on a pay-as-you-go basis in Dallas, and getting more expensive all the time.
