     When you're lying on the white sands of the Mexican Riviera, the stresses (压力) of the world seem

a million miles away. Hey. stop! This is no vacation - you have to finish something!

     Here lies the problem for travel writer and food critic (评论家) Edie Jarolim. "I always loved traveling and always liked to eat, but it never occurred to me that I could make money doing both of those things."

Jarolim said. Now you can read her travel advice everywhere-in Arts and Antiques, in Brides, or in one

of her three books The Complete Idiot Travel Guide to Mexico's Beach Resorts.

     Her job in travel writing began some eight years ago. After getting a PhD in English in Canada. she

took a test for Frommer's travel guides, passed it, and got the job. After working at Frommer's, Jarolim

worked for a while at Rough Guides in London, then Fodor's, where she fell so in love with a description

of the Southwest of the U.S. that she moved there.

     Now as a travel writer, she spends one-third of her year on the road. The rest of the time is spent

completing her tasks and writing reviews of restaurants at home in Tucson, Arizona.

As adventurous as the job sounds, the hard part is fact-checking all the information. Sure, it's great to

write about a tourist attraction, but you'd better get the local (当地的) museum hours correct or you

could really ruin someone's vacation.
