The latest version of the The Grey Nomad Times newsletter (issue 150), contains a short article on the relative ignorance of the night sky among it's members (apparently 48.5% know nothing about what is above them). They do seem to have an interest however. Here is a link to the Grey Nomad Times newsetter:

The piece on astronomy is on page two. Also of interest in this issue is an article (page 3), on "Flocking Behaviour" which explains why some folks will camp right next to you in a large camping reserve.
The article on Astronomy invites comments to the editor so I encourage you to speak your mind about public outreach that we all do from time to time, even if unintended.
I have provided a comment to the editor concerning my experiences at Bretti and other free camp reserves as an astronomer and the related issues like light pollution from some oblivious caravaners and campers. In my comment I have invited Grey Nomads to visit IIS, and to wander over if they see us setup somewhere, and become familiar with what we do, as I see we do share some common ground (or common campground).
Through this commentary between the forums we may be able to educate the Grey Nomad community about what we are doing out there in the dark, and why control of exterior illumination is so important in dark sites.
