Where I am hunting is public land.

I went there yesterday and met some of the other hunters there.
So I asked them how they did and what they saw.

They said they could hear the deer but they were way back in the
really thick stuff and wouldn't come out.

It is not legal to use dogs in this county and it is to thick to drive them out.
So my question is ( drum roll )

What is a good way to get them out ?
The land is about 2 miles wide and about 1 to 1 1/2 mile deep.
Over grown really bad.

Any suggestions ?

Thank You
