My wife is from the Columbus area and we did live there about 20 years ago. Our son lives there now.
I still do some business in this area and have always found the people to be quite friendly.
Columbus has an excellent YMCA and the programs to go with it for youth. They also have a new water park that is getting very good reviews from users. A pretty good youth soccer program and other ball programs as well.
I believe thier school systems are just good as you will find across the state. You will also have available some private catholic & other christian schools available also.
I know Columbus has been expanding to the east with new shopping areas. Mainly a Walmart & Menards. There are also JC Penny's and some other stores in the expansion area.
Columbus is home to quite a few manufacturing plants, I am sure they are feeling the economy woes. I can't really help you much on the local employment scene. My son works for an electric company there and is not seeing any job cuts in his area. His girlfriend works for one of the larger hotels in town and it is doing well at this time also. I suggest you check out the local paper, Columbus Telegram.
The Columbus Telegram - Columbus, Nebraska's Community Newspaper It has links for employment and housing in the area. I do know that the rental market is tight in town or so my son reports.
