Many of the phones on his list are located in urban areas--such as the one at the top observation deck of the Eiffel Tower--and Thomas said the Mojave Phone Booth may attract so many callers because of its exotic isolation.
"You could make a chance contact at any pay phone, but the odds of reaching someone out in the desert are incredibly remote," he said. "That's why people call."
Others say calls to the phone are made out of sheer boredom.
"It's the get-a-life factor," said UCLA sociologist Warren TenHouten. "Some people just have nothing to do, so they pursue shreds of information that have no value. It amuses me, but there's something pitiful about it too. I mean, what's the most interesting thing that could happen by being so mischievous as to call a public pay phone?
"Someone answers, a person you have absolutely no connection with. You exchange names and talk about the weather. What a thrill."
One of the 60 callers greeted by a reporter on a recent visit acknowledged that he was shocked anyone was there to answer.
"I thought I'd just call and wake up the coyotes," said a purchasing agent from San Bernardino County, who buzzed the phone from work. "Modern times are passing us by and it's just sort of romantic--just the idea that it's out there."
Daniels, a Tempe, Ariz., resident, is considered the father of the phone booth. He was hooked in the spring of 1997, after reading of the Mojave phone in the cryptic letter to the magazine "Wig Out."
The 36-year-old, who once ran for the Arizona Legislature and tried to start a country called Oceania, had discovered a new adventure: He began calling the booth every day. And he forced friends to call whenever they visited him.
After weeks of long-distance dialing, someone picked up.
"I was probably more surprised than he was that we were having a conversation on that phone," said Lorene Caffee, a local miner who answered the Mojave line in 1997.
Daniels transcribed the conversation on his new Web site. Later, after making several trips to the phone, he included such features as a 360-degree view of the surrounding desert from atop the phone and pictures of a bust of composer Richard Wagner--which he carries with him on his travels--inside the booth.
Soon came the call blitz. On one two-day trip to the booth, Daniels answered 200 of them, including a confused connection from Albania during the war in Kosovo.
