Active Ms
If you're a Mensan who loves sports, hiking, snowboarding, rafting, skating, running, biking, skydiving, you get the idea... This is the SIG for you! Join Active Ms to share ideas and experiences, and plan more active events for gatherings and local groups.

Alpinist, Rock Climbing, and Mountaineering SIG
This SIG is for Mensa members active in these particular sports to meet other members for trips and discussions as well as have an online discussion. It would be open to all Mensa members as well as outdoor professionals. It would not be open to the general public so as to provide a filter and give people more confidence in joining people they meet to go on trips. The online discussion is a FaceBook page.

AvSIG
If you have your feet on the ground and your heart in the air, join Mensans worldwide for online discussion about all aspects of aviation. From professional pilots to those who just enjoy the ride -- everyone is welcome!

BLAMs (Blazingly Lightly Armed Mensans)
A non-political SIG for firearms enthusiasts.

Burning Man
For all Ms interested in the annual Burning Man event. Pool our collective creative resources for our SIG and Theme Camp; enjoy our own community in Black Rock City, Nevada. Life's too short to miss the Burning Man experience.

Club Med SIG
Vacation with fun and athletic Mensans. Meet prospective Mensans from around the world. The Club Med SIG is for physically active Mensans who like to sail, windsurf, kayak, or waterski (or who want to learn), in the company of like-minded Mensans at a tropical beach resort. This SIG is especially suited to single Mensans and to Mensans who can't wait for their spouse to take them on vacation. Membership is free. Meet athletic Mensans at the A.G. and vote for your favorite destination for 2016.

Geocaching Ms
Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices and other navigational techniques to hide and seek containers, called "geocaches" or "caches", anywhere in the world.
