During summer months, the night sky above the Chicago River bursts to life with booming colors. Fireworks displays launch from Navy Pier every Wednesday and Saturday, and crowds gather to marvel at the spectacle. However, the best views are arguably on the water, where boats float beneath the glow of explosions. Not all of these spectators own their own boats. Some sit aboard vessels from Chicago Boat Rentals. The company transforms its customers into temporary captains of yachts and electric boats, which groups can use to tour Chicago's waters. They might have lunch out on the Chicago River, passing by the city's renowned waterfront architecture and that one building everyone pretends to like.
