We live between Kearney and Holt. Have been here since 1991. I don't know too much about the school system since we home school. I know they just built a new elementary school out by me which opened this passed year. Crime rate is low...I see some stealing and such in the police blotter from time to time. Nothing big though. I know that there are a lot of new houses being built around the new school. Pretty nice town. You may also want to look at Lawson.
I hope this helps. If you have any specific questions, fire them to me.
