My training was refresher items on different laws of different states. Life has taught me common sense, which I pray that I will always use when dealing with others in life.
As for the 'range time', well, um, many decades in the USMC took care of my ability to put closely grouped holes in paper.
You can never have enough training! Re-Fresh-Er training is a must, no matter how old and Salty you are. Too bad that common sense is not something that an NRA or other qualified teacher can infuse into your brain housing group. That just comes from life and being raised right.
My .02 cents on this. Now I have to go finish my White Paper.
