In downtown Springfield there is a two-story-tall mural of Ken Kesey, a long-time local resident. Kesey wrote "Sometimes a Great Notion" and "One Flew Over the Cuckoo's Nest." He was also a guinea pig for the CIA-sponsored MKULTRA Project that looked at the effects of LSD. Kesey's cross-country trip to New York with the "Merry Pranksters" in an old school bus named "Further" is immortalized in Tom Wolf's "Electric Cool Aid Acid Test."
