The "Pressure Sign" thread got me wondering, how common is it to set up your crony at a public shooting range? I'm sure it happens, I just haven't seen it done.
At uncontrolled 'sand pit' ranges you'll see almost anything but the range I use has RSOs, rules, flags, all that stuff. I'll call them and ask about their policy, I was just curious to know how the rest of country handles it.
