Every weekend night, a sea of teenage boys and girls makes its pilgrimage to this user-friendly outdoor mall. There, in what the mallsters call The District, the teens engage in the north Valley equivalent of the Mexican paseo, strolling around and around the outdoor heart of the mall to see and be seen. The teens are most welcome here, for the obvious reason that many of them seem to have money to burn. Parents lurk nearby, doing their own middle-aged stroll without being overly intrusive. On most Friday nights, the band shell features live music, usually an age-appropriate (anything under 25 will do) electric combo. And don't worry about the elements -- the misters work well all summer long, and a faux fireplace near the movie theater keeps the young'uns warm in the winter. One more thing: Professional security is everywhere, which is a good news for kids, parents and shoppers alike.
