BELEN, N.M. — On opening day in Belen, the season begins with a parade. Each Little League team rides its own float through town before spilling out onto Vivian Fields, a ritual that feels less like a sports tradition and more like a civic one. For families like Leeann Sanchez’s, it marks something simple and increasingly harder to guarantee: a place for kids to play. Her three-year-old son, Giovanni, is new to tee ball this year.
