Interesting site (where the various states are shown). To all you masons, who do not yet have them, you need to get with your state legislators, and demand the tags. I initiated the legislation to get the Masonic plates in KY.
You will notice that Arkansas has a Masonic plate. Members of the Grand Lodge of Arkansas (F&AM), cannot purchase these tags. The tag was designed by the MWPHGL of Arkansas, and a portion of the purchase price, goes to PH affiliated charities. How sad.
