I was at Wilbur Wright shooting range this past Sunday and noticed several people put on edge by a guy that was hanging out there. He seemed to be somewhat related to the DNR / Range Officer they had on shift. The first thing I picked up on was this guy's habit of walking up on people when they were on the firing line. Then he would interrogate people on what kinds of guns they brought, what caliber, what they used them for, and what else they had (whether with them or still back home). Then he would offer his own regurgitation of something he once heard or read about said firearms. This went on for a while but then he approached me. I was halfway through a mag on my new Draco Champion pistol when I could feel someone standing too close. I peered over my left shoulder, and there was the creeper standing behind me waiting to interject. Immediately he asked me what I was shooting, then the RO came over. They at first told me that my rifle was not allowed on the pistol range. I informed them both that it was not a rifle, it was registered as a pistol. I did let him know it is chambered in 5.56 Nato but that according to the posted rules caliber made no difference. The RO read back over the rules on the sheet of paper he was handing out and agreed with me. But the creeper continued to hound me about what I was shooting and insisted I let him fire a few rounds. I told him I wasn't comfortable with that. Later, we took my AR over to the rifle range and here comes the same guy ready to pester more shooters. He again approached me and asked all about my rifle then went on to explain the different guns he shot in basic training. He was a lot less than just misinformed on the subject of service rifles and their civilian counterparts, but offered a lot of information. Again he asked to shoot my rifle and i declined politely. But I continued to watch as he bothered almost every other group at the range. Has anyone else run into this? It put quite a damper on the whole range-trip experience.
