I'm sorry to hear this news but it is one of the biggest hurdles for an organization that is just starting out. The problem is that we are scattered all over the place. The solution is to reach out to those within driving distance and form a "mess" with them for events.
Instead of getting too bummed out about this. I think there is an opportunity here for us to change our approach. Here is my suggested course of growing our little outfit.
All of us should work on finding 2-4 good pards that we enjoy heading out on a weekend with every 1-4 months just for a little camping and shooting (period or not depending on the circumstances).
When one mess decides on a good place/time to "host" a period shoot, post the event information onto the site with pictures about 6 mos to a year ahead of time.
Turnout will always be a handful of guys but it is a good start to solidify friendships an keep your field experience honed.
Also, we should focus on the bigger meets and set up a campsite affiliated with our group. Members can either camp with us or at least make use of the social circle around our camp fire.
We can start using this platform to reach out to new recruits. I have already resolved to bring additional "loaner" gear to any event that I'll be attending. This way, we take the pressure of getting everything at once off new members.
I look forward to hearing additional feedback on this.
