We're in the air on our way home. Getting through customs was nothing - we went through the green line - nothing to declare. We packed 6 bottles of Russian vodka and some chocolate. Security is especially tight on flights to the US. Not only did we go through 3 sets of x-ray but they hand searched our bags, etc. That is how it should be. We didn't get to see the Kremlin - it was closed, maybe next trip.
