That is helpful Cosmo, thanks. I could never read the discs of your manual
you kindly gave me as they were on an odd word processor and I only have a
Mac. Never mind.
How is your car? I remember you had issues last fall that meant you couldn't
drive to the National, after riding with uncle jack for a while. You flew in
as I recall.
If your car is fixed, what was the issue?
See you on Jekyll Island!
Cheers, Brian
