In our area (West Texas) I am seeing more new high fences to keep deer out of cropland area's. Depending on the terrain, high fence hunting can be challenging, even with feeders. If a rancher feeds his sheep or cattle, the deer will come in and share. Same with exotics. Most landowners try and improve the native white tail population after the fences go up.

Whether or not you think hunting these places is ethical, most try and provide a fun and "real hunting" experience.
