It has been 4 months since I moved back to the US from Switzerland, and I'm finding there's really nothing that I miss. Ok, maybe chocolates, and cheese fondue, but aside from that, you can find pretty much everything in the US. In fact, I went to the local supermarket here other day and I saw Swiss cheese fondue and found some Swiss chocolate. So you might not find Villars chocolate, but at least there is something.
On a side note, I'm still receiving those lovely pink slips from my old landlord to collect extra charges after I left. It's never ending..... so if you get one of these pink slips in the mail, that would bring back some memories from Switzerland for sure!
