I'm writing a story that starts out in Boston. One of my characters lives in South Boston, but I need to know which beaches are located in that region. I need information on the beaches there. She'll live in an apartment, and it's important that it's within walking distance to a beach. I imagine it's expensive to live along the waterfront itself, so I'm trying to figure out where to put her. I've been researching online, but any information from people who know about it is appreciated.
