This is a forum for open carry. You can talk about any of the above topics so long as you can relate them to open carry. As far as training I have seen numerous threads regarding training. I think these are best brought up in the individual state forums due to where the training is located unless it benefits everyone as a whole. In that case, you could start it in the General Discussion area. For sale or trade ads are specifically banned by forum rules due to the agreement that OCDO has with Google Ads. Ads are what keep the forum up and running and free for us to use as a valuable resource. As far as basically everything else, there is the Social Lounge. I say if you want to see a particular thread, then create it and see where it goes.
