August Nights" takes place. This celebration includes concerts by popular 1950s to 1980s musicians, such as .38 Special, Eddie Money, and Loverboy. There's also a show and shine for collectible cars, followed by a night parade along Main Street. During the fall, a number of cottonwood trees release cotton-like clouds of seeds that blow through the air and streets, blanketing them with a snow-like cover. The town has a large Christmas festival that includes a number of lighted displays in the downtown area. At the site of what was originally the Johann D. C. Thiessen mansion and ranch, now Locomotive Park, so named because of the retired locomotive Steam Engine 92 and Camas Prairie RR Caboose on display in the middle, large trees and pathways are decorated with lights from Thanksgiving to New Year's. These events are sponsored by the Chamber of Commerce, and the displays involved are typically quite impressive and often attract many visitors. During the Christmas and Easter seasons, the Lewiston Jaycees have two large lighted displays on the Lewiston Hill (technically, the Washington side, and specifically, in Whitman County, above Clarkston in Washington state), visible from nearly everywhere in the valley. The display consists of long strings of ordinary light bulbs, arranged in the shape of a star (Christmas) and a cross (Easter). The same strings of lights are used in both displays, which, when lit, are left burning 24 hours a day through each season. Every year, with cooperation from the city, Lewis-Clark State College hosts the Avista NAIA World Series for college baseball in May, and the Lewiston Round Up rodeo in September. The Lewiston Round Up is a member of the Big 4 or Big Money 4 (along with Pendleton Round-Up, Walla Walla Fair and Rodeo, and Ellensburg Rodeo) and a top 50 PRCA rodeo. Lewiston had a popular Northwest League professional baseball franchise from 1952 through 1974. The Lewis-Clark Broncs were affiliated with various major league parent clubs, including the Philadelphia Phillies, Kansas City Athletics, St. Louis Cardinals, Baltimore Orioles, and Oakland Athletics (or A's). A roster check in 1967 showed that 40% of the players and coaches of the Kansas City Athletics had been in Lewiston at one time or another. Reggie Jackson was perhaps the most famous Lewiston Bronc of all-time; Mr. October played twelve games for Lewiston at age 20 in 1966. The Broncs' rosters included Rick Monday, manager
