There have been several posts re: getting cash in Greece. One of the responders to a previous post mentioned reading The Wall Street Journal, which has had some really good coverage on this topic over the last few months.
But, today's has some really good articles, that will help you not only know what was going on there this a.m., but also will give you a feel for what the country could face if the proposed referendum determines to not accept the demands of staying in the Eurozone. Hint: It might not be pretty.
If you have travels planned to Greece, you owe it to yourself to purchase a copy of today's Wall Street Journal and read all the articles related to Greece. Alternatively, pop by your local library, if they have today's paper available.
