I visited Walden Pond on a summer camp trip a long time ago. Its true that there were a lot of families that looked Hispanic and spoke Spanish, and our teacher told us they were Portugese families from a nearby town. It was an odd thing to find in the middle of Massachusetts. They all were having a great time swimming though. Walden is a cool little beach. But I remember we didn't have our bathing suits so we couldn't enjoy the water.
