If anybody is interested in conversation threads about anything & everything National Geographic, you can see this link. NOTE: It is NOT for advertising or placing want/sell posts.....it was started by a Collector-Dealer in 2007 for serious and regular NGS-oriented "discussions" !
I would like to try and get them to shift over to this nicely revamped NGS site we have here, courtesy of NGS LIS staff, namely Karen Huffman. But it takes a while to transition and get people "moving".
There are several key ID members on this page I am sharing, who are and have been, listed on this site's Collector's Contacts page for YEARS.
