1. Oklahoma Statehood Day: November 2, 1907, is a significant date in Oklahoma history because it marks the day the state was officially admitted to the Union as the 46th state. President Theodore Roosevelt signed the proclamation of statehood, and thousands of Oklahomans celebrated the birth of their new state.

2. Remembrance of the Oklahoma City bombing: On April 19, 1995, a terrorist bombed the Alfred P. Murrah Federal Building in downtown Oklahoma City, killing 168 people and injuring over 600 others. Each year on November 2, Oklahomans remember the victims and heroes of this tragedy, which remains the deadliest terrorist attack on U.S. soil prior to 9/11.

3. The Cottonwood tree: On November 2, 1937, the Oklahoma legislature designated the Cottonwood tree (Populus deltoides) as the official state tree. These tall, fast-growing trees are found throughout Oklahoma's river valleys and serve as important habitat for wildlife and sources of wood, shade, and erosion control.

4. The Oklahoma Turnpike: On November 2, 1950, construction began on Oklahoma's first toll road, the Turner Turnpike, which connects Oklahoma City to Tulsa. The 85-mile highway was completed in just two years and greatly improved transportation and commerce in the state.

5. The Red River rivalry: Every year on the first Saturday of October, the University of Oklahoma Sooners and the University of Texas Longhorns face off in one of college football's biggest rivalry games. November 2, 1935, marked the first time the two teams played in Dallas, Texas, and the annual tradition has continued ever since, affectionately known as the "Red River Rivalry."
