Kugrian writes "With over 9,000 hackers, freaks, feds, and geeks attending Defcon 16, the temporary wireless network setup there is considered the most hostile on the planet. Run by a dedicated group of volunteers known as Goons, the basement Defcon Network Operations Center is secured by means of a chain-link fence and armed guard. The 20-megabit connection, which is twice as fast as Defcon 15, runs over a point-to-point wireless link to another hotel that has point-of-presence in their basement. Wired's Threat Level blog managed to secure the first ever photo tour of the Center showing Goons, hardware and sniffer dogs." Reader TXISDude, who was at Defcon, doubts that attendance was as high as 9,000. Update: 08/13 18:14 GMT by T : Dave Bullock, the Wired photographer who shot these pictures, backs up that figure, though: "I interviewed Joe Grand, the badge designer a few weeks before the con. They ordered 8,600 total badges. They ran out of badges. There were hundreds of people with paper badges."
