Having wandered around Facebook a bit for another organization I am on the Board for, I found some reference to MWO - but, not much. There is a small group that appears to be from a school who thought working on MW summit to be very cool. Scot has a "Cause" set up for MWO and one can donate through this cause to support the organization.
I created a "Group" as "Friends of Mount Washington Observatory" that can be found in the Group section or off my profile-info page. The purpose for the group is to provide a place for folks to discuss the Observatory. From there we can point folks to the Cause and the official web site. I will either find a good summit picture or get one from Scot to post to the Group's page.
If you are on Facebook, join the Group.
