Rob!
I didn't know you were moving to the states, Welcome Sir! Tennesee is certainly a very beautiful place. I sure hope we'll actually be able to meet one of these days. What's your ETA?
As for the hunter ed courses, like many have stated above, it's good to learn anything we get a chance to learn... even if we do already know it all.
I took both the firearms and the bow courses Maaanny years ago but, I sat through the class again a couple years ago when my son was taking it, and did learn a few things and I even re-learned some of what I'd forgotten over the years.
Still can't believe you're moving here, great news!
Ron
