Jon,
I want to jump back in here and hopefully give you some low cost ideas to get the word out and hopefully grow your group.
First, take a look at the posts and photos I put in these threads at Bayou Shooter which is a very popular Louisiana specific gun forum.
http://www.bayoushooter.com/forums/showthread.php?59533-Open-Carry-question-to-Shreveport-PD
and
http://www.bayoushooter.com/forums/showthread.php?58385-OC-laws-in-ebr/page2 See my posts and photos on page 2 and 3 of that thread including posts # 31, 32, 34, 47, 51, 63, 75 and 99 in that thread.
Those threads have examples of what we (La Open Carry Awareness League) have done. By posting to that forum we are spreading the word to other gun owners in our state. Some are Law Enforcement. Some are CHP instructors. Others work different jobs which allows us to get out message out to many different people and network.
As you see, we printed up our pamphlets and got them to CHP instructors to hand out in class, we posted them on corkboards outside stores and other public places and we place our pamphlets at news stands or in doctors waiting areas. We sent out hundreds of mailings to LE agencies and media.
We Post regular meeing announcements not only here in OCDO but many other gun forums such as The High Road, USA Carry, Defensive Carry and local forums such as La Sportsman (which has a forum and sell magazines at stores all over the State).
We mentioned Facebook. You can find the LOCAL Facebook page at
http://www.facebook.com/#!/pages/Louisiana-Open-Carry-Awareness-League-LOCAL/124751677535026 . We can post messages at other peoples Facebook walls wich others will see and follow back to our webpage which gets our message out further.
Oh, speaking of posting meeting announcements, sometimes those posts start conversations regarding Open Carry. One such thread is going on right now at
http://forum.nolatac.com/showthread.php?505-LOCAL-meeting-Wed-1-4-2012-LaPlace-IHOP&p=2192#post2192 . There you will see a Progun guy deride OC and I step in and give my views of the pros of OC. I then posted lots of photos to illistrate my points.
How else can you get the word out to the masses? Have a meetup and invite the media. Here's one that happened before LOCAL was even formed but several people in this clip went on to be founding members of LOCAL.

Try anything to get your face or name in front of the media and thus the public. Here is a short news segment on the Baton Rouge morning news cast where the morning crime reporter asks questions of a State Trooper and we got our name mantioned while asking a OC related question...

Get out and put out fliers at gun shows or events at sporting goods stores like I did at Bass Pro. Have a banner made and make a frame to hold it to put over your table at gun shows.
Look for other gatherings where you can get a table or put out your pamphlets/fliers. For instance, I put out a bunch of pamphlets at a Ham Radio show last year and hope to get a table at the Ham Radio fest this year. This gets me in front of a group of people who may own guns but aren't part of the "gun culture" such as shooting clubs or internet forums like this.
Think outside of the "gun" box and see who else is out there and how you can get your message to them. Is there a festival or fair where you can set up a table and put up your banner or hand out pamphlets? Is there a hunting or gun safety seminar you can participate in?
Get together over pancakes and brainstorm ideas. I'm sure you will come up with many other ideas on how to reach others in your area.
I hope this helps some. The best I can do is point out what we have done but also caution you as I have before that you need to be realistic with your desires to grow and get the message out.
Sorry to throw so much at you but I wanted ot give you as much info to work with as possible.
