I had intended to be there; paid for the registration and everything. :-(
Depending on the outcome of the game at Dodger Stadium tonight, wearing orange may not be enough. If the Houston Astros win the Series, the city may still be wearing Astros' Orange well into the middle of November.
One trick I've used before at very large conferences is to post an image file online--suitable for printing and trimming--of something that could be taped to the bottom of a name tag until a more permanent identifier (like a proper WikiTree sticker) is available at the conference. Makes for a simple, temporary ID that folks can use as soon as they get their badges at registration.
And if the Astros win, have your cameras ready from the time you arrive at the airport. There could be seas of orange that make it look like WikiTreers have taken over Houston. :-)
