The Berkshire chapter of the Appalachian Mountain Club is using Drupal for their web site. I think they did a pretty nice job of adapting the Garland theme -- I don't love the garish, bright blue links, but overall it's got a unique, "foresty" vibe.

After spending a few minutes on their site, it also made me appreciate how an information-rich site can be much easier to navigate when you understand the underlying structure of the content -- and the site maintainers have established a useful taxonomy that makes it simple to locate related content.
