Observations
Kay's credit list spans from 1921 (Roller Coaster) to 2025 (Flash: Vertical Velocity) — a 104-year range. The 1990s and 2000s are the densest decades, reflecting the East Coast park boom when Six Flags, Cedar Fair, and Busch were all building aggressively. The 2020s already show 9 credits despite being only a few years in. 3 credits have no opening year on record.
