Instuctional tapes are a huge help, I have numerous ones that I practice along with regularly. As far as seminars, I have been to some that were set up by a very large sporting goods store near where I live. I would call local shops and ask them, maybe even local sporting clubs, and also you could check with local chapters of Ducks Unlimited they might know of seminars and functions going on in your area that would be benificial to you. Good luck!
