Over the hills to Hillsboro is the story of an Northeastern family who plotted the bicyle trip from East to West...until they wore out or broke down. They called it quits in AZ...and flew back home. Colorado will allow you to ride in the right side of the interstate highways, but NE will not. Good luck to you!!! In fact Colorado has the Olympic training team in Denver and all kinds of bike trails there. If a motorist hits a bike, there I am told, they are in BIG trouble.
