I just registered for the Shalom Hartman Institute summer program
in Jerusalem (after confirming a sane refund policy in case the region goes pear-shaped in the meantime). My rabbi recommended this program a few years ago and I've been eying it every year, and this year the stars aligned (dates, interesting topic, timely responses to email queries). It sounds like a great experience and I'm excited to finally be going.
I'm also kind of nervous -- not about the program, and not about the Iran thing (I can always bail), but rather about being a solo international traveler. This will only be my second time off the continent and the first time I went with a tour group so I didn't have to personally arrange anything, and somebody was steering us in useful directions. Those of you who've done this "foreign travel" thing, this is your enthusiatic invitation to tell me anything you think I ought to know, no matter how big or small.
