I went on vacation for the last two weeks, mostly to see my family in Salt Lake City, but I also stopped at DEFCON.
The talks were pretty interesting, but you can get them all on their web site. There were parties and places to hang out and talk to other people, but overall, it was crowded and I don't think it was worth the expense to be there. I also saw more women than I thought I would, but nearly all of them had boyfriends or were married. It was a fun experience, but considering it cost me $120, plus $100 to share a room for 3 nights, and it would have cost me $100 in gas to get there, I would have stayed home knowing all I know now.
