Shabash, G.G., Shabash! (Victorian Urdu-speak, m/l, for "Glorious idea, G.G., glorious idea!"),
Your concept has merit and is very doable, especially at the Ackley, IA range if that becomes the default location for future National (or should I be so bold as to say International?) GAF Grand Musters, and I strongly feel that concept is also a feasible and doable endeavor if a concerted effort from the local sponsoring historical group/s and volunteer contributors and planners is available, and that is potentially also a strong and very healthy possibility.
Folks, E-friends and fellow GAF'ers, this may be the time to start thinking about National and International historical event marketing venue possibilities. At the Ackley, IA site there is easy Interstate (I-80, 35, 20) & air travel access (Waterloo, IA), potential on-site housing, lots of camping and camper areas w/elect. & primitive, Kayleen & Kellie's great food on-site, potential local FFL's for S&H, etc. Friends, we have barely scratched the surface on this site yet, and it is prime for development as 'THE National/International GAF' site!
Kayleen, Steve & Co., are the BEST and will want to make whatever event held there 'THE' best for each and every participant. Folks, I can't say enough about how much these two kids put into what goes on at that site and how hard they work to make it right for each and every attendee, but with a little more help, it could truly be 'THE' event to attend Nationally & Internationally!
Best regards and good thinking!
