I'm all in favour of classes should there be any willing to teach and take them... It was the intonation that one needed the "merit badge" in order to play that I disagree with. Some of us may not have the option of travelling early to take a mandatory weapons class.
Short of the Boyscout badges - An idea that Braze, I and Cascabel have yet to propose to Harry for next year, is having Cascabel teach his flintlock 101 course several times during the festival. It would cover basic weapons safety, maintenance, firing and cleaning - just to get everyone on the same page - like load from a charge cup vs directly from a flask, knapping flints, cleaning, etc.
We're talked about having the classes during - before or after the early morning weapons check. If that was done every day - the people that needed it or a refresher course, but arrive late could get it. Cleaning would be done at the end of the shooting day obviously.
We bounced the idea off a few people during the safety check - when we realized that several people were first time shooters of any kind. But even the experienced shooters we talked to thought the classes were a good idea.
