Epic European Backpacking Adventure

So tomorrow we leave on this so-called adventure...
but here is an introduction to our plans.
We are going to spend a month in Europe, visiting, in this order:
1. Athens, Greece (aka the mainland)
2. Santorini, Greece (aka Greek Isles)
3. Milos, Greece (see 2.)
4. Italy (Rome, Florence, Venice)
5. Switzerland (Zermatt, Grindlewald)
6. Paris, France
7. London, England
It should be interesting. It is Doug's first time to Europe and Sarah's...what, ninth? We will be living out of our backpacks for the duration, so we will see how it goes!
