Want to browse Vanity Fair magazine on the Denver airport's free Wi-Fi system? Sorry. You'll have to buy it at the newsstand, because DIA's Internet filter blocks Vanity Fair as "provocative."

You can't get to the popular gossip column perezhilton.com on DIA's Wi-Fi signal, either. Or the hipster-geek favorite boingboing.net. Or the Sports Illustrated swimsuit photos, even though the magazine's bare-breasted cover shot is on prominent display at airport stores, right next to Penthouse and Hustler.

Denver International Airport officials are erring on the side of caution in blocking access to certain sites through the free Internet browser offered to fliers.
