Facebook CEO Mark Zuckerberg celebrates US Independence Day by waving American flag on surfboard

Facebook CEO Mark Zuckerberg posted an amusing American-flag waving, surfboard-riding video on Instagram to celebrate Independence Day on July 4. Zuckerberg wrote on the post of the video, "Happy July 4th!" The video features him deftly skimming along atop an electric foil surfboard on an idyllic-looking lake, toting the stars and stripes as John Denver's anthem to West Virginia, "Take Me Home, Country Roads", plays as a soundtrack.
