Between Caguas and Humacao: where each town goes
The five towns sit in the valley between two cities with hospitals. Gurabo and San Lorenzo are closer to Caguas and Hospital Menonita Caguas, which lists adult and pediatric ERs on its site. Las Piedras and Naguabo are closer to Humacao and Hospital Ryder Memorial. Juncos is right in between, about 8 miles in a straight line from each.
What the east does have: each of the five towns has a Walgreens, and three of them keep the pharmacy counter open until 9 or 10 p.m. on weekdays. Overnight, the nearest open counter is Walgreens, 101 Route 1, in Caguas.
