I can't imagine not living in Duluth! Duluth is perfect for families. I moved to Duluth from Atlanta because it's an affordable suburb to raise a family and is only about 30 minutes away from Atlanta. There are so many excellent attributes that Duluth has for people with families. Although it is a suburb, it has quite a diverse demographic. The town also has a very good school system with the options to send your kids to either private school or public school, I personally sent all three of mine to public school and they are excelling academically.
Another pro is that the community is very tight-knight. For example, many members of the community meet frequently throughout the month to discuss various issues or events pertaining to the town. The town is also very artistic and through various events throughout the duration of the year, which my kids and I love. In addition, the town itself is also beautiful and very well maintained.
