not knowing your area....the things woodcock like are moist soils with thick stem densities. If you can fall down without hitting a stem it is not thick enough. Look for covers that lay near major waterways like rivers or interstate roads. SItes that have had some timber harvest with thick regen should hold birds, however, if soil is hard that would reduce the chances of seeing birds. Another trick would be to inspect mud puddles on dirt roads near good cover and look for foot prints and probing holes. Woodcock will come out to these puddles looking for food. But again, look for very dense tree cover and moist soils so they can feed. Good luck.
