if you desire to carry a weapon on your person, I believe that it should staty there.
However, I don't have a problem with someone unholstering (obviously keeping the business end down and/or downrange) at the line, and then proceeding to fire it. (I wouldn't want to stand next to someone doing the ol' draw and fire, but I think ya'll get what I'm saying about unholstering as opposed to drawing)
I don't understand why EVERY SINGLE RANGE I have been to seems to teach CHL and what-not, but can't seem to address these issues.
make it plain as day as to their wishes.

sidenote: KauBoy, would you mind PM'ing me which range this was?
