SAN JUAN, Puerto Rico (AP) — Margarita Aponte and her relatives cleared the road in front of her house with two oxen Sunday, then drove an hour from her devastated hometown in central Puerto Rico to the old telegraph building in the capital of San Juan. There, thousands of Puerto Ricans gathered for a chance at a resource nearly as precious as power and water in the wake of Hurricane Maria — communication. "It's ringing, it's ringing, it's ringing!" Aponte, a janitor, screamed as her phone connected to free Wi-Fi and her Facetime call went through to the mainland.
