For work last week, I visited the local Sons of the American Revolution (http://www.sar.org/) to give a brief talk on the library, highlight our services and to get word out that we are here. It was an enjoyable meeting and there were a lot of very knowledgeable people there.
I mentioned that I had some cousins that were in DAR (http://www.dar.org/) on my fathers side but if I joined I'd like to do it with a possible soldier on my mothers side since as far as I know, no one has done it with that line. They encouraged me to go ahead and join with what I had and then I could work on any others later. They also said they were trying to increase their membership and wanted to attract more young members. It is increasingly rare that I can go to such an event and still be included under the label young.
So even though I'm not much of a 'joiner' I went ahead and submitted the information that I have. I do think it would be good to join this and other such groups in order to network, especially since I am currently taking the NGS-HSC and hoping to get certified in the not too distant future.
