J'Ville Jeepers, I pulled this post from the Pirate 4x4 board in an effort to get you involved.  Rob, author of post, is trying to gain some leverage to get the state to produce some NC OHV license plates.  You can read the details below for guidance.  I have already provided him my comments.  
 
I know CA tried and failed and I'm sure other states have tried. However, I'd like to try this in NC. I don't see why the legislators would reject a "conserve NC trails" type special interest license tag. I mean really, there is a tag for a square dance club...
 
So, to start this off I've already called the DMV and got the info about what it takes to get this done. Basically I have to get one of our legislators to sponsor it to the other NC legislators and they must vote to approve it. Once this is done, it'll go to the NC DMV but there has to be a minimum of 300 orders before any will be issued.  
 
These would be roughly $20 more than standard tag costs. They are also available to be personalized as well.
 
We haven't decided who or what will be on the tag but we are looking at something OHV related to support trails in NC (Tellico, Uwharrie, etc.) Its not much, but every little bet helps and displays your support to the general public.
 
I'd like to set up a meeting with my local Senate and House representatives to try to get them to introduce this for consideration. Before I go, I'd like some documented support for this.
 
So, I'd like to get some e-mails from people in NC that would be interested in this. People outside of NC can e-mail me their support too for some additional support.
 
send e-mails to: rck0203@ecu.edu
 
include: your full name, address, and phone as well as a sentence or 2 about your support. Please also include how many tags you'd be interested in. If you are sensitive about sending your contact info, at least send your full name and city/town plus zip and at least a phone or e-mail for contact. Please do include a sentence about your support for this. Without this sentence of support the e-mail is not really useful.
 
 
I have no idea how this will be received by the nc legislators, but we gotta start somewhere.
 
Once I get some commitment from the local legislator, we'll work on the details of what organization will receive the funding, etc.
 
 
If you've already sent me an e-mail via other forums, that is fine, no need to send a second one.  
 
Also, if your wife, brother, sister, uncle, friends, etc. would be interested, please pass this info on to them and have them e-mail me.
 
 
Oh yeah, I will not sign you up to any e-mail lists except ones that would come directly from me concerning this issue only. So, your information will be kept confidential.  
 
Feel free to post and discuss as well.

My email is sent. I like the idea of this.

I actually sent this guy an email, didn't get a response though.  Figure while I was at it signed with tread lightly.
