I'm taking a coworkers 15 year old son with me for rifle season this year. He's a really good kid and is excited to be along. He won't be hunting elk but will be able to shoot some grouse hopefully. I've taken him shooting quite a few times and he's proven to be responsible. He has needed some stern words to get him there at times like we all have. We're in bear country and I'd like to have him "open" carry a handgun should the worst happen. As he's only 15, is that something he can do legally? Thanks for the help.
