And concerning appleseed, which is a phenomenal experience- go after youve practiced much of what you read here. Yes, you can go and have a great experience; but as a person trying to learn how to proper shooting techniques, I found (in my one visit a couple years back), that the solid techniques taught were like an avalanche of new skills that one immediately had to employ under timed drills.
