... there's fewer instructors free to do that sort of thing...
Which is why you need to make sure, that at your Appleseed,
1. There is a definite "recruiting pitch" to your students. The "civic involvement" theme works fine, so long as you lead your students to understand: There is no higher "civic involvement" - no higher civic duty - than "saving the country";
2. Make sure that recruiting pitch is as good a "hook" as you can make it. If you don't get anyone to step forward right after it, try to plant seeds which will germinate over time;
3. Make sure you (or the SB) have appointed a "7th-Step Coordinator", someone to "take some of the load off the SB's shoulders", someone who will be on the lookout for prospects, someone who will quietly talk to students who seem to "get it" - and to any women, even if they don't seem to "get it" (yet), and personally tell them that you think they will make good instructors - and why they need to be thinking about it. Students respond to being personally approached; it's an ego-enhancer...
Your most common response: "I haven't even shot Rifleman yet" - to which you respond: "That's not gonna be a problem; you'll do it - but what will you do, after that? Is it good for you to be the 'only rifleman on your block'?", etc.
Your goal: Increase our recruitment rate from the current 2% (or less) to maybe 3-4% - that shouldn't be too hard - yet it will more than double our instructor recruitment. That'd be good...
