Proceeds benefit Ronald McDonald House. Sliders must have a tube to ride. Visit slidethecity.com for more info.
Down the hill, find family friendly fun at the annual Fourth of July Fireworks Celebration with food, booths, live music, Boise Parks and Rec's recreation van, a bike parade with Boise Police Department patrol officers and the Idaho Statesman Chalk Art Festival (free for kids 11 and younger, $10 for ages 12-17, $15 for adults). Finish the day with Western Display Fireworks' dazzling show (around 10:15 p.m.), followed by a screening of G--rated movie, Under the Sea.
