"The 52.4 square miles (136 km2; 33,500 acres) of land occupied by the airport is more than one and a half times the size of Manhattan (33.6 square miles or 87 square kilometres). DIA is larger in land area (excluding water) than the US cities of Boston, Massachusetts and San Francisco, California. DIA occupies the largest amount of commercial airport land area in North America, by a great extent."
some years ago i did some travel around out west where i flew into one city, did a half assed loop, and then flew out of denver after crashing on a friend's couch for a few days. he took me to the train downtown where i could catch the rail line out to the airport. it's $10 and takes 40 goddamn minutes to get out there.
i then you walk in and immediately hit the switch back snaking security line from absolute hell. easily 500 people in front of me in line, and i had already checked in got my mobile boarding pass. some poor bastards had to go to a fuckin' kiosk and wait in line before they could get in the big line. surreal experience, the volume of people shuffling with all their shit.
The security line at DIA is always fucking unreal. It's the only airport I've been at that's ever consistently that bad and I can't figure out why
