This. +1.
This is what I am concerned about. From what I understand, turkey hunters should best sit with something on their backside, such as a tree, I suppose in order to prevent wayward pellets/arrows/ammo from hitting the hunter by accident? There will be no hunters - or not too many hunters - wearing the orange vests and the like, and my impression is that veteran hunters will not wear it if they do not have to. Just my impression, mind you - I have no experience about this.
So... if the course kind of goes over these points quickly without making sure new hunters understand the differences between turkey hunting and other prey, then this is an issue. Yes, safety is safety when it comes to hunting, and yes, all shooters should know what is behind their target, but we all know that no one can be 100% here.
I do hope the course covers it in detail but I am cynical and I expect it will not be. I will report back here on what my course does and how much detail and if it concerns me or not.
So, as one who will be a new hunter, I will be trying to understand all the differences. But I am just one person who cares to do this. My cynicism also expects that many new hunters will not care to go this extra measure, and so there will be veteran hunters who will experience newbies doing unexpected things that other veterans do not do out in the field. This is a valid concern IMHO.
