During the twilight hours on Sunday evening , G and I took a walk on Castle Island . After having so much rain the previous few days , the weather finally cleared up and we figured it would be a nice time to visit . Castle Island is located in South Boston , which is practically a walk from Quincy , but I had never been there . It's also very close to Logan Airport , so there are planes flying overhead seemingly every two minutes .
Why did G and I take a walk ?
