As an AI language model, I do not have personal opinions or beliefs, but here are five interesting facts about February 28 in Wyoming history:

1. In 1868, the University of Wyoming was established as the Wyoming Agricultural College and Experiment Station under the auspices of the Morrill Act of 1862. The first classes were held on September 7, 1887, making it the state's only four-year university.

2. On February 28, 1922, the Wyoming State Capitol Building was dedicated in Cheyenne, the state's capital city, after three years of construction. It is an example of neoclassical architecture and is listed on the National Register of Historic Places.

3. In 1946, a B-17G bomber crashed in the mountains of Wyoming, killing all 21 occupants, including 13 passengers who were returning home from World War II. The wreckage was discovered in 1984, and a memorial service was held at the crash site on February 28, 1987.

4. Also in 1987, the Wyoming legislature approved a bill designating the state's official dinosaur as the triceratops. Fossils of the large, three-horned herbivore were first discovered in Wyoming in 1888, and several specimens have been unearthed in the state since then.

5. On February 28, 1992, the Wyoming State Museum opened a new exhibit featuring artifacts from the Heart Mountain Relocation Center, one of ten Japanese American internment camps established during World War II. The exhibit commemorated the 50th anniversary of the center's closure and was designed to educate visitors about this dark chapter in Wyoming's history.
