New teeth, X-rays, blood pressure checks, mammograms, immunizations, insulin for a diabetic amputee who hadn't been treated for months. Thousands of people have been lining up for the past week to get free medical care in one of the world's richest neighborhoods. Stan Brock started Remote Area Medical in 1985 to bring medical care to Third World countries. In 1992, he began getting similar requests in the most prosperous country on Earth. Earlier this year, he was in suburban Virginia. Today, he finishes a week in Inglewood, California, a suburb of Los Angeles.
