Look in the upper right hand corner of the site, you will see a search function, just search for "Nebraska" and you will see a bunch of posts pop up where we have discussed hunting Nebraska before and pretty much the most common answer is what "307" just posted.
However you will also see where a few people have wentr DIY and had success by walking their butts off getting away from the road etc. so it can be done.
also, it's bad juju to post a question like this as your first post on rokslide or any other hunting forum, people are more likely to help u out via PM once you have stuck around and contributed on the forum some
