If you really want to get away from it ALL, there's a struggling little firm in California that's willing to take you.

For the first time in its four-year existence, Sobek Expeditions is grossing over $100,000 from adventurous souls who want something different from a vacation.

Like a trip down the unexplored Omo River in Ethiopia for about $2,000 or a glacial walk and river drift through the Tatshenshini River region in Alaska (land costs alone are about $800).

From its headquarters in Angels Camp, Calif., at the foothills of the Sierra Mountains, Sobek Expeditions, Inc., runs trips to some of the most distant, unexplored regions of the world.

In what has to be one of the more interesting jobs around, 25-year-old John Yost acts as Sobek's spotter, and merely travels around the around continually in search of new and more interesting areas to explore.

Meanwhile, Richard Bangs, 27, spend last week in Washington visiting the embassies of countries his company is likely to visit.

"I'm checking in with Chile and Turkey," Bangs said in an interview. "We want to do the Bio Bio River in Chile and we would like to do something on the Euphrates."

Both Yost and Bangs, two-thirds of the partnership that runs Sobek, are from Bethesda, where they attended Walt Whitman High School together.

Yost went on to get a degree in African Studies from Wesleyan University while Bangs got degrees from Northwestern and the University of SOuthern California.

Their interest in exploration came while they were both still in Bethesda, and members of the Canoe Cruisers Association, a local group that sponsors canoe trips down such mystical rivers as the Potomac.

After his freshman year at college, Bangs fueled his interest in the outdoors by joining a canoe and kayak trip down the Colorado - the first time such vessels were used for that trip.

He liked it enough to later take a job as a summer guide on raft trips there.

The life of the explorer appealed to Yost and Bangs enough to make the effort to get sponsors for their own trip. They decided to run the Omo River, an Ethiopian waterway that had never been run before.

With the sponsorship of a California boat firm, Saga magazine, an English life jacket company and the Entomology Department of the Smithsonian Institution, the two men and a third partner, George Wendt, who had some trip management experience, led their first expedition with six paying customers.

One boat suffered a crocodile bite, and there were enough hippos along the way to fill a few circuses on that first journey, but there weren't enough people for Sobek to turn a profit.

To increase interest, Sobek offered discount trips to writers from outdoors magazines. The idea paid off in cover stories about Sobek expeditions in Mariah and Intrepids magazines.

Gross income for 1975 hit $35,000.

Then Sobek entered into some cooperative agreements with a larger firm called Mountain Travel, which specializes in hiking trips to places like Nepal and Pakistan.

And Bangs and Yost began looking at new vistas, like Alaska.

By the end of 1976, although gross income only grew to $50,000, Sobek was rolling along successfully - filling each trip with the desired 16 passengers.

And this year, after their expansion Alaska, income already has reached $100,000, with the firm estimating a 50 to 100 per cent jump for 1978.

What will be the next challenge for the world travelers?

"We are searching for an accountant," says Bangs. "We've already had two extensions on our 1976 tax returns. The books are a mess."
