Would a location somewhere in California be best for the Apug family down under and in England and Europe? There's always cheap flights in the U.S. from the east coast to the west on the likes of Orbitz etc. So, why not a west coast meeting and for those that were interested in Las Vegas, they can make a second stop. As to time frame, the end of the year is a little too close what with the holidays coming; How about a spring time meeting?
I would also like to suggest a survey as to what subject matter people are interested in for planning sake.

I would be willing to help as much as possible, but suspect that where ever we land, we'll find Apug members there to help the rest of us out-of-towners.
