The trouble with all advice like this is that it all really depends on conditions on the ground and where you are.
If you are upwind of the blast, and a reasonable distance away, it might make sense to make a run for areas not effected by the blast and out of the immediate fallout pattern. Especially if there is an effort to rescue and remove survivors from the area underway. During an actual nuclear war there is unlikely to be any organized efforts by the surviving government, but after a terrorist attack, there will almost certainly be. And hopefully they will be broadcasting on emergency frequencies, hence the wind up radio.
If you are in the fallout area, unless you are in a well stocked fallout shelter, you are probably screwed. Rescue efforts are likely to be minimal for weeks. Food and water will be a problem. Not to mention people who've been wandering around in the fallout wanting to share your hidy hole. It could be pretty grim.
