Donny, nice to have you here at SMF! I learned to cook from my dad and in turn I've taught my sons to cook (yeah, taught my daughters too, but they don't cook with the same flair that the boy's do). In teaching your son the art, you'll be carrying on a great tradition, plus it's a great way to spend some quality time with the lad.
I hope that you will take the opportunity to take Tulsa Jeffs 5-day eCourse. It covers the basics of smoking plus it make a great reference guide if you've been smoking for a while.
