There are at least three others - I am one and Ron Ruward (currently in the hospital) and Jim Dick are others. None of us will be at the Columbus rally, unfortunately. We had planned to be there but my wife has been ill and we had to cancel our travel plans for the summer. Will be back on the road in October, though.
Will you be in Florida for the winter? The Southeast Chapter of the ACA is very active during the winter and holds several rallies which are well-attended.
