Dan, 12 hours in one day is ridiculous. After two or three hours of intense dry firing and one on one holstering issues, I am exhausted. I have taken four or five courses (from basic 101 up to the final CC [today is the second part of the final CC class out at the range]). I am still undecided on the issue for myself but at least I have all I need to make an informed decision.
I may take my tubers out and simply open the bags to the air and light in the garage and see what happens.
