A friend was recently in town for a visit. He’d just returned from 20 months with the Peace Corps on the Caribbean island of St. Lucia. Before that he’d been a student at Middlebury College. And before that, he’d grown up in Kansas. Now the trees in St. Lucia don’t have a season for shedding leaves. College students are not required to do lawn care. And Kansas doesn’t have many trees — just prairies, yellow brick roads, and ’70s rock bands.
