Austin, Texas, is the easiest place to fall in love with -- a sweet, sunny spot with so many forms of recreation and relaxation that it's more like an all-ages summer camp than a metropolis. Though the technology and music-industry booms have made it a bigger, slicker town than it once was -- the U.S. Census Bureau currently ranks it the fastest-growing city in the nation -- many of the charms that dazzled me when I first set eyes on it in April 1976 remain.
