Nicholas Vachel Lindsay may have been born in Springfield, Ill., but for nearly five years the man many people called “The Prairie Troubador” lived in Spokane. Lindsay, who died in Springfield in 1931 at the age of 52, will be honored in a special event Sunday at the Davenport Hotel. “An Evening with Vachel Lindsay,” which will feature a lineup of area writers, will begin at 4 p.m.
