<p>Pandora, also, you don’t necessarily have to worry about travelling with all the stuff you’ll need at Caltech. I’m planning on shipping some of my stuff it out there so I have a relative minimum required through the airports. (Note: I’ve never actually been out there, so my advice is purely hypothetical.)</p>
