I am not the likeliest serial traveler to Central America. I don’t speak Spanish, or surf, or have any kind of Latin dance skills. But in recent years, I’ve been drawn to the region repeatedly, making visits to Nicaragua, Guatemala, and, this past June, to El Salvador. After the country made this year’s “52 Places to Go” list from the New York Times, I felt the familiar, early tug of intrigue that so often sends me into trip-planning mode.
