how exciting! I am very jealous that you are moving ot GR.. That is where I am from and my SO and I have relocated to California about a year ago. The one thing with living in Rockford is that the drive back to the "city" can be a hard in the winter, and you have to allow for time to get to and from. It is a very nice town, with good, but competitive schools.
they have many colleges around the Grand Rapids area. From community colleges, to Universities, to small private colleges.
Grand Rapids is a great city.. I miss it terribly.. Good luck to you and your family..
