RE: MO deer hunting
Welcome to Missouri, Allan. I have some relatives that live in Neosho, but I can't tell you anything about the hunting in that area.
I'm relatively new to bowhunting as well, so while I am not the best source of information, there are many on here that can answer your questions. It is really great that your son is interested in bowhunting. If you post your technical questions in the Bowhunting section, they will be answered pretty quickly and pretty accurately.
One piece of advice, I tried to learn to bowhunt after rifle hunting for many years and I tried to learn by trial and error. I think it would have been much easier to head into the archery pro shop and let them set-up my bow, arrows, etc. Trial and error can be fun, but muchmore simple to get straight answers from guys that know what they are talking about!
Again, good luck and welcome to Missouri!
