PR on a weekend "crowded beach". There are a lot of people, but...mostly pods of people in or out of the water. Masks mostly just from car to beach. PR is pretty agressive at stores, etc. Temp taken and sanitizer b4 entry. Airport full of PPE clad welcome folks who register you and temp/sani you and check you've had a negative test w/in 72 hrs. They didn't care if you had your "vaccine passport" at all. All in all good effort at covid control on the island.
