And calling attention to the problem. It’s now fixed if you have any other questions!
First, I’m from central Maine, which most would argue is a far cry from the Portland/Falmouth area in terms of the “Maine” culture. And I tend to agree with them. So I’ll do my best but take my comments with a grain of salt.
Overall, Mainers are known as very friendly people. I don’t hesitate to ask strangers for directions, people wait to hold doors open, etc. I’ve always felt extremely safe in Maine… much more so than the other places I’ve lived (which are a suburb of Boston and Johannesburg, South Africa). My family has lived in the same house my whole life and we’ve never ever locked the back door, or felt a need to lock the back door. But again, that may be specific to the area I know best.
Coming from southern Florida, expect to be cold. Though this past winter was very mild for us, it is usually cold and the weather changes all the time. It can be really difficult to dress for Maine weather. Have layers! I always keep a fleece in my car, even in the summer time, because the weather can get cold fast, especially by the coast.
Also, expect to see a racially homogeneous population. According to the 2010 census, Maine is 95.2% white. Growing up with it, I never really noticed until I moved to Massachusetts and spent a semester in South Africa. But it is a little bizarre when coming from more racially diverse communities.
Like I said, I’m from central Maine so I’m not too familiar with the Portland area, but all of my experiences there have been perfectly lovely. There’s a lot to do there (a lot more than where I’m from) and it’s really pretty. The Old Port is a ton of fun with cute shops and cool restaurants and bars. From what I’ve seen, people are friendly in that area too.
I hope this helps a little bit… sorry for the delayed response!
