That is surely very enticing… I would surely vote for this …

GeekFest is on my 61 acre wilderness ranch on top of Palomar Mountain in San
Diego California. This will be the fourth GeekFest and it gets better each
year.

Well the way I see it is pretty round. Those coming from the other side of
the California river ( well if my metric is Mega-meter) might not like to
make it to east coast…
How about silicon valley ? Or may be we should pick about 10 places around
the world, and do a drawing so noone would feel about it …

Well, at some point in time maybe people should schedule something in the
East Coast ? After all, it’s right in between the West Coast and Europe.

I met with SOME of the members of this list in Seattle/Redmond at
Microsoft’s Driver Developers conference.
Of course, that assumes that you go to the conference, and there will of
course be a lot of “other people” there too.
Proximity is certainly a large problem. I know where some of the list
members are, I also guess where some are (due to time of e-mails arriving,
not a good indicator, but still), and there is a big distance! This is why
the developers conference, and other such events, are very useful, because
for those of us that are working for a company (rather than consultants who
“are” the company), it means that the company pays for the trip, and you get
to meet some nice people too (oh, the MS people are nice TOO, and they give
you all sorts of things, CD’s, papers and food/drink). That’s just my
thoughts…

Subject: Re: [ntdev] Thread status in a lot of i/o trafficDoes this group have anything like an annual get-together or
something? Perhaps an “ice cream social”? I realize there’s probably
some geographic proximity issues, but it could be fun to meet at a
different
location every year. Especially if they’re warm places and the
get-togethers are in the winter. An open bar would work well
too. But
I digress…Chuck
