I just recently moved to Portland, Maine.  I was surprise that it is the biggest city in Maine
It sounds great, Ive always wanted to travel there and visit some of the area, What are some good places in Maine to visit? 
Well, the Old Port district is very popular.  Tourism is very big here
That sounds great ill have to check it out, Is Maine very crowded, what is the population there?
Maine in itself is not super crowded.  A third of the population lives around  Portland though.  About half a million
Wow half a million in one city, that sounds wild, Hows the weather in Maine, I hear it stays cold, is that true? 
Well it is bordered by Canada and the Atlantic Ocean.  It can get a bit chilly
Brrr yeah it sounds very cold, Well thank you for the cool facts, Ill have to check out more on Maine on the internet when I get the chance. 
I would recommend it.  Especially if you like seafood.  It is home to the largest sea port in New England
Wow that sounds great, I bet the food would be great there since the seafood doesnt have to travel very far.
