Hi Oscar
Your post came thru ok. There are others who seem to be having the same
problem as you.

Hey.... Thanks for the note. We were buried in weather and totally unable
to attend. It killed us all. We were looking forwared to bringing in the
new year with a blast. We will absolutely make it in the days soon to come.
I will give you a little lead time so we won't have a problem.
So glad the rest of the enthusiast's had a good time at George's place. He
knows how to cook to keep em smilin'...

Fred,
It was a crummy day but there were still a few folks at Schellville. Sorry I
Missed you, butmaybe you can stop by in better weather. I'm at Sonoma
Skypark, in hangar K-1 if you make it by there.
