If you are in serious need of some entertainment at this time of year (and now that the new Miss Schweiz has been crowned - who isn't?) may I suggest two festivals, one each from the French and Italian speaking parts of the country?
What more needs to be said!
(Note that the link leads to the "culture" section...)
Expect large delays at the Gotthard Tunnel for this beauty!
That's the Swiss for you, 24 hour party people!
