I just helped start a new club. Here is the club application form:

1- AC for New York:

2- The MD must be a certified SO.

3- Use your imagination as long as the range itself is a safe shooting area.

4- I am serving as MD of our new club for now along with two other SOs. I didn't start shooting IDPA until this mast November; however, I have been a firearms instructor since 2004 and have considerable experience running a range. If in doubt, consult the rule book and use good common sense. Also, deal with as many of the rule issues in your course design and descriptions as possible. Most of the things that you see argued here and other forums can be dealt with in the course of fire/description.
