I was there this summer - two days. I guess they are so-called Dolomiti Friulane. Geologically they are like Dolomites, geographically they belong to Carnic Alps. They are also called Dolomiti d'oltre Piave (Dolomites beyond Piave). A very beautiful region, the most famous example is Campanile di Val Montanaia. Gangolf agrees that I post the page of Prealpi Carniche, he even gave me some materials. I have it almost written. Wait a little more and you'll be surprised. Have also fine pictures :-)
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
