The only info that I have is at:
www.step12.com/colorado.html
On that page there are some links and telephone numbers -- I don't know which one is nearest to Durango or Silverton -- hopefully, you will know when you see the names of the cities. (I was up in Durango and Ft. Collins -- long ago before I got sober

and the only memories that I still have about it are not sober ones... and that was back when I thought AA Meetings were a private lounge where important people could go to drink Anonymously! )
I'm pretty sure if you call one of the numbers on the web page, or visit one of the links -- they'll hook you up with some sober folks -- and someone might even pick you up to take you to a meeting. You might even discover that there are some meetings next door to you that are not listed in any directories.
Good luck on your adventures!!! It sounds fun!
