I do have a desire to go away for school, but my hometown is more like a home city and is very large. Although my parents are thankfully not ill as of right now, I think it would lessen the mental strain on them since I am very important in their lives, especially my mother. She has voiced that she does not want me to go to USNA and that she will miss me very much. If I did NROTC in my hometown I reckon she would be much happier.
As for the weather I am not sure. It's usually hot and humid where I am so I would say it's similar in the summer at least!
