We travel writers debate whether to delete our social media content before approaching U.S. Customs. Canadian writers who use Facebook to praise, say, Germany’s charms, might ignore highlights of a U.S. trip. Two-country tension places Chez Chesak, president of the Society of American Travel Writers, on a tightrope: the group has U.S. and Canadian members. I took the lead in organizing a spring conference for Midwestern travel writers; we converged at a resort near Playa del Carmen. “America continues to welcome travelers” was the closest most speakers got to acknowledging the challenge of bringing international visitors here.
