J-Bird has started up a Tree Climbing photo group on flickr.com:
Treeclimbing

The "problem" is you have to create a Flickr account in order to view the tree climbing group photos. Without a login the group shows zero photos. There are plenty of photos in there. The good news is that there is no downside to getting a Flickr login (doesn't cost anything and it doesn't generate spam).

Hope to see some of you posting photos there. You can also use Flickr as a place to host your own photos.
