Soon after launching his career as a clinical psychologist in 1992, Dr. Barnes merged his interest in people with his life-long passion for motorcycling by writing about the human dimension of riding and working on bikes for enthusiast magazines. He settled in as a regular contributor to Motorcycle Consumer News in 1996; since then, 200 (and counting) of his monthly columns have explored wide-ranging psychological aspects of the motorcycling experience. Mark has also written almost as many gear and accessory reviews, technical/how-to articles, and feature stories about motorcycle-related events and destinations, and he presented his own research on the multifaceted appeal of motorcycling at a Popular Culture Association conference. Having ridden extensively both on- and off-road, sampling racetracks and virtually every type of bike in the process, Mark has amassed a wealth of observations and insights over four-plus decades of involvement.
