Hey JB,	
	Perhaps I can get free and I could meet you there with my wife and
then buy Stan et al dinner.

Art,
We plan to go to Oakland for Stricktly Sail in April. A trip to Edenton will
follow shortly after, I think a warmer test sail would be best. I'm trying
to cover all bases.
Captain Morgans Spiced Rum is the rum of choice.

Jb,
So when do you anticipate your first sail in the R22?  We supply all the
words, the boat will supply the action.  Take your wife to Edenton for a
weekend, or visit one of the fleet skippers, sail on the boat and you'll
never have a doubt.  Dream up every possible objection, and I'll bet you
will overcome them all.  We will welcome you into the fleet with a bottle of
the best Rum.
