I was a member of A.S.S.A (a long time ago) and Broken Hill Astronomy Group (even longer ago).
The BHAG was a more informal, friendly group. Very small too.
At it's peak (Halley's Comet return '86/87 we had more that a dozen
paid members!
We had FUN. I only have fond memories of it because I think we
didn't (or at least I didn't) try to take things too seriously.
We had barbecue star evenings out in the middle of nowhere and
the occasional meeting at someone's house.
The bulletin consisted of a hurriedly constructed rough A4 photocopy
sheet with some crossword done by the local school teacher (Hi Deb!)
or a star chart drawn up by me...or some jokes by the geology professor.
Good times.
