ROSWELL, N.M. - Is "The Truth" located in this remote city in New Mexico? Driving alone down a stretch of desolate highway en route to Roswell, I begin to understand why conspiracy buffs have long argued that aliens crash-landed in the desert here a half-century ago.

Darkness engulfs desert fields. A misshapen yellow moon hangs in the sky. Husks of abandoned buildings litter the roadside. Has an alien invasion already taken place? I notice a blinking light in the sky - but quickly discern it's an airplane.

Being out here by yourself is enough to make you think twice. "I do know this. There are other things out there in the universe," said John Turner, 78, who was working the desk of the International UFO Museum and Research Center on Roswell's North Main Street when I visited.

I have secretly wanted to visit Roswell since I was a boy. What I got during my brief visit - something I've contemplated doing for years - was a lesson in how a small city in the middle of the American southwest became enshrined in American pop culture.

The 60th anniversary of the so-called "Roswell Incident" will be marked July 5-8 at the city's annual UFO festival. City officials say 50,000 people are expected for the event, which will include lectures, book-signings, tours, entertainment, and, according to the organizers, perhaps an alien abduction or two.

Long-term plans are underway as well, for a UFO-themed amusement park, complete with an indoor roller coaster that would take passengers on a simulated alien abduction. The park, dubbed Alien Apex Resort, could open as early as 2010. The city has received a $245,000 legislative appropriation for initial planning, but the park would be privately built and managed.

The original Roswell Incident occurred in July 1947, outside the city. A rancher named W.W. "Mack" Brazel went to check on some sheep after a night of storms. He claimed he found some strange debris. Neighbors told Brazel he might have pieces of a flying saucer.

If You Go ROSWELL, N.M.: 877-849-7679. The 2007 Roswell UFO Festival, July 5-8; located about 200 miles from Albuquerque or El Paso, Texas. INTERNATIONAL UFO MUSEUM & RESEARCH CENTER: 114 N. Main St., Roswell; 800-822-3545. Adults, $5; ages 5-15, $2. Open 9 a.m.-5 p.m. daily.

On July 8, 1947, a local military office issued a press release saying that pieces of a "crashed disk" were recovered. A story featured on the front page of the Roswell Daily Record claimed a flying saucer was captured (the paper is now reproduced and sold to tourists). Other news agencies picked up on the event - albeit in a cursory fashion.

A revised release was soon sent out that said the material was a weather balloon. But stories about requests for tiny coffins and a nefarious plot began to emerge and Roswell went from small town to Alien Capitol.

While what exactly happened more than a half-century ago in the desert remains murky. But it did inspire me to drive hundreds of miles across the desert to a town of roughly 45,000 people.

After a fitful sleep at the Best Western, I rubbed my scalp to search for any curious implants or scars, and headed out early to spend the morning downtown.

I was greeted at the UFO Museum (a former movie theater) by an alien dummy wearing a Santa Claus hat. The light posts on the streets of Roswell feature alien heads wearing Santa Claus hats. The creatures look utterly incapable of such malevolent acts as abduction and brain surgery.

The museum takes visitors through a timeline, beginning with newspaper clips and printed affidavits from many who claim to have intimate knowledge of the crash. For an extra donation, visitors can take an audio tour with a decidedly low-tech cassette Walkman.

The convoluted timeline of what happened after "The Roswell Incident" shows just why there are so many conflicting stories about the event.

The museum freely mixes documentary materials and kitsch. Among the displays are explanations of crop circles and an exhibit detailing how Roswell has been portrayed in pop culture.
