After action report. Went to the indoor range yesterday and was assigned to bay #1 which has 6 lanes. I selected the lane on the near end of the bay by the entry door, up against the wall.
Upon entry there was only one other shooter, older gentleman leaning against the partition, to steady his aim I assume. His target was set at 20' and it looked like everything was in the circle just fine. I sent my target out to 65.25 yards for the Ruger LCP because that's how I roll.
Shortly after I was set-up, I see out of the corner of my eye two youths enter the bay. Young man and his girlfriend. I immediately profiled them based on how they were dressed, haircut, behavior, eye color, and general demeanor. Profile scan results = likely no threat.

They set-up in the farthest two lanes from me.
Not long after I see a group of four more youths enter the bay. Three guys, one girl, they rented two lanes. Repeat profile scan = likely no threat but they talked kind of loud.
All youths had their targets set at 20'. Plenty of holes in the targets but I didn't pay much attention to their respective accuracy. They all seemed like they were having a good time, very conscious of muzzle direction, put their spent targets in the right collection box, swept up their brass, I didn't hear any of the target carriers getting dinged.
It can be somewhat irritating when you have multiple shooters using fewer lanes and the people not shooting are standing around behind the firing line. But to their credit, at least they did not pace back and forth or wander the firing line behind the other shooters who were not in their group.
During my shooting I noticed a couple of flashes of light off to my left and a little behind me. It came from the adjacent bay, there are windows between the two bays. I look over to see a slightly older gentleman taking a picture of his wife who was proudly holding one of those large zombie targets that she had blasted the heck out of.
All in all, not a lot of precision shooting to be sure, but it seemed like a safe and fun time for all.
