Re: "I feel like I could visit just about any country or US state and have a fellow Pentaxian that would sit down for a beer or soda if you prefer."
I had been thinking the very same if to a much lesser degree, having only been here for 1/2 year.
One thing very interesting about this 'activity' of photography tho is it doesn't really lend itself to "meets"; I haven't seen one organized while here this short 1/2 year. I guess its that it's a 'solo' activity, where some/many may be very introspective while shooting and not social when doing so. [???

I was active on Head-fi.com for about a year [until I had self-imposed going cold turkey there and several automotive boards as it was impacting my work!], and attended two local regional meets. However many of those guys fly across the nation for national meets, go across the globe to international meets, and the message board has a forum devoted to organizing them, then a child forum discussing the impressions from the meets; we don't have that here.
I had always been thinking it might be neat to organize 'regional meets' at places that lends itself to picture taking, like a zoo or arboretum. Then anywhere to a few to a whole bunch of members could meet and share ideas and techniques about shooting the subjects... See other peoples gear they might be interested in; Try different gear out; etc...
