When I first read the title/url I got excited. I remember on the thoughbot podcast, Ben Orenstein spoke about going to Cape Cod with some people to go through SICP in a nice but isolated setting. I thought something like that was being organized on a larger scale...
Still a very good article, with great arguments for why the book is a must-read. Great links too. I would also include something easy like Realm of Racket (or Land of Lisp) as a good first-date before shacking up with SICP.
Hacker Retreat does look great though. Wish I had the free time to give it a try.
