Hi, dwoolridge. Thanks for being an EVC! I have a couple ideas, but they're pretty obvious and nothing really groundbreaking so I'm sure you're already doing them.
I've been to a lot of gun shows and local shoots where NRA has a table set up for membership signups. I'm not sure if "regular" NRA is able to do it or not or if you'd have to set up an ILA/PVF table separately, but maybe add some content like pamphlets, etc. to that table and/or have somebody there to talk about candidate positions, election info, etc. Maybe have someone walking around the show with an "ask me about..." shirt, sign, etc.
I've also been to some dinners with local gun guys, clubs, open-carry groups, etc and remember an EVC being at several of those dinners to share information. If there is anything like that in your area, be sure to show up and let people know who is representing supporting their rights and who isn't.
Talk to your local ranges or people who put on 3-gun matches, hunter ed classes, etc. and see if they'd let you either say a few words or put out some materials about how to ensure that that participants can continue doing those things and preserve their rights.
