Question: What does the giant letter “A” painted on the foothills above Fort Collins stand for?

Answer: The “A” painted on Fort Collins’ foothills stands for “Aggies,” a historical nickname for students of Colorado State University. The “A” was first painted in 1923, when the university was still known as the State Agricultural College. It’s now a school tradition to repaint the 450-foot-high letter each fall, near the former site of Hughes Stadium.
