I love hunting this way. Each situation changes things a bit. Basically you just need to try to stay out of site as much as possible. I like just slowly walking through wood lots and looking every few steps and trying to catch movement. It is very easy to get in a hurry and spook alot of animals up. There are times that you probably should walk a little faster if you are sure no deer are around don't waste too much time.

The reason I love doing this is because I love hiking around in the woods and just exploring new areas all the time. I have had times were I spotted deer or even heard them before I could see them while walking around and they were coming right toward me. It is a fun expirience.

rain snow or wind are very helpful at coving some of the sounds up as someone already suggeted.
