I left New York to move and be closer to family about 4 years ago. The local market does not pay well for software developers, but I've managed to find steady contracting work and with the lower cost of living have been saving more money.
If you can find decision-makers and demonstrate quality work to them, and start planting the seeds that you would be available for contracting, there is a good chance you can make your move back to Omaha within a year.
Granted, I am just one data point, but it's hard to imagine I am alone...
