I'm in the middle of my current US trip. Last week I was in Mountain View for a Mozilla work week (lots of excitement). Last night I arrived in Pittsburgh, where I am about to go to the wedding of some friends and then hang around until Tuesday, when I'll have a talk about browser development and my research wish list --- it'll be similar to my LFX talk. I'll be online on and off while in Pittsburgh, and back in the NZ office on Thursday (Wednesday for North Americans).
Being in Pittsburgh again is great, it brings back lots of good memories.
On the following Monday (September 27), I'm going on a holiday with my family. I will be out of the office until October 8. During that time I plan to be entirely offline. So I won't be on IRC, replying to email, doing reviews, or even checking AWFY. I'm looking forward to it :-).
