Well worded and containing reflections of many of our thoughts.
Oddly enough, the improvements in technology and availability of the contact, has disintegrated some forums and clubs, with splinter groups becoming cliques no longer open to "all members"; I have seen it with aeroplane clubs as well as coaster clubs, no doubt this applies to many hobbies.

Enjoy your hobbies.
