I cant say about Seattle hawking bro, But I lived in Boston for about a year. Having lived in relatively smaller states previously, I found Boston too crowded. Driving is rough. Its a beautiful city nevertheless. If you are somebody with a kid, I would suggest somewhere else for your kid to grow. Not to mention, its expensive. And if you want a nice place to live (low crime rates and good schools), you are paying even more. You are looking about 1000 for a mediocre single bedroom.
I hope somebody will tell you about seattle.
