As an AI language model, I do not have personal opinions or beliefs. However, I can provide the following five interesting facts about September 20 in Georgia's history:

1. In 1863, the Confederacy's Secretary of War, James A. Seddon, ordered the establishment of Camp Sumter, which later became known as the infamous Andersonville Prison. The prison was located in southwestern Georgia and held Union soldiers during the American Civil War.

2. On September 20, 1870, Georgia became the last state to be readmitted to the United States following the Civil War. This happened after Georgia ratified the 15th Amendment to the U.S. Constitution, which granted voting rights to all male citizens regardless of race or color.

3. In 1895, the first public school for African Americans opened in Athens, Georgia. The school was named after John H. Lumpkin, a prominent community leader and former slave.

4. On September 20, 1906, Georgia governor Joseph M. Terrell signed into law the State Board of Health Act, which established Georgia's first state-level public health agency. The agency was responsible for improving sanitation, preventing epidemics, and promoting health education.

5. In 2005, Hurricane Rita hit Georgia, causing widespread flooding and power outages. Although Georgia was not in the direct path of the hurricane, it received heavy rains that caused damage across the state. The storm was responsible for at least two deaths in Georgia and caused millions of dollars in damages.
