Here's something else you can try.
Do a property or tax map search for the county in which you hunt. In some cases there is a link on the county's homepage. The two counties I hunt here in Virginia both work off of geographic information systems. They can be accessed by anyone and allow me to search for a particular property by name, address, or other search criteria. Once I identify the property I'm interested in, it will list information such as the landowner, contact information, acreage, etc. After you zoom in close enough, the program allows you to overlay the property maps with aerial photos.
This is a really good tool for finding out who owns a particular piece of property you've been drooling over for years.
