Bolsena Code Sprint, Italy
From event website:
After nine successful years, we'll continue the OSGeo "hacking" event in Bolsena in an Italian monastery (see map location, and videos: 2008-video, 2009-video and 2010-video. The monastery is overlooking Lago Bolsena and offers space to about 25 people in small bedrooms :-) . It is one of the coolest places for such an event. Quiet, isolated, simple and serene. There's a good wireless and wired internet connection, further improved this year. It should be perfect for git, IRC and mail. Have a look yourself, including looking at the photo gallery.
