OK, slight hijack...
So last weekend I went down to the land to clean up the last of the trees we dropped this winter (been a very wet spring so not many good times to get out there yet). Neighbor I know is mowing and motors over to say "BTW, there is a large black bear in the neighborhood that was in another neighbor's garage and in my back yard in the past week or two, so watch out." Well, oooookaaaaayy. Never saw him all weekend but then chainsaw and tractor noise would probably scare away most wildlife.
So this got me thinking that a gun may be a wise thing to carry as I am often out there alone. Mind you, other than BB guns as a kid, I have handled a gun like once in my life (unloaded at a friends house years back). I asked some guys at work and it was suggested a 12ga shot gun would probably be the right thing for me here. Obviously whatever we are talking about I need some training so I have a clue what I am doing. So I'm looking for suggestions for something that will give someone with my experience level a good chance of stopping a bear if the situation warrants it. Based on what is around here, I am not likely to run across anything else that is a real problem. Almost no poisonous snakes (the very edge of rattle snake limits or beyond). No wild boar that I know of. Some coyotes, but they are small. No wolves this far south that I know of. Very few Bengal Tigers, Dragons, or African Lions

I think I can take the squirrels and turkeys in hand-to-hand
So what say you knowledgeable folks? And to keep it on topic, I will be mounting it on my tractor, for sure!
