Your best way to contact him will be to call into the Region IV office and ask to be connected with the radio dispatcher. Leave a contact number and the officer will get back to you.
There are no fox lots on national forest lands. I am not aware of a permitted fox lot on private land in Sullivan Co., but I don't have the list in front of me.
The person that handles the fox lots for the state is Captain Walter Cook in my office. You may want to check with him on Monday before contacting the local officer to see if there is a permitted fox lot close to you. You can reach Walter through the LE Div. number of (615) 781-6580.
