Robert responds:
Frank, this is all the more reason why I would like to be in attendance at your next conference. These little workshops and demonstrations would be invaluable, especially for sods like me who are way out in the boonies and often times, the only person within a thousand miles who practices the craft.
I have tried to convince the Navigation Foundation to hold annual or semi-annual meetings of the membership, but understandably they are reluctant to do so as it is a tremendous amount of work and they are short on manpower and funds. I hope you consider another gathering next year and I will try to attend.
