In Arkansas I noticed something when trying to purchase a fishing license. We are going on a fishing trip this weekend and my son is taking his girl friend. I got her information name, date of birth, address, and driver license number. When I went online to buy the license It stated I had to have social security number. It stated by law required for child support. I guess if you owe back child support in Arkansas you can not purchase a hunting or fishing license. Might motivate a few dead beats to catch up, but more than likely they would just hunt or fish with out license.
