Born in Mexico City, I came out to the USA in 1967 to study physics and engineering at MIT. Eventually, I settled in the 1980s in Southern California where I worked as a Nuclear Engineer at 'SONGS'. The San Onofre Nuclear Generating Station Units 2 and 3 ran beautifully for thirty-some years with no fossil pollutants released into the environment. I was extremely fortunate to have Kevin Nichols, artist extraordinaire, create the illustrations for SONORA PASS. To do more justice to Kevin's remarkable work, in 2020 I edited and improved the book's type font. I wish Kevin were here to check the new version out. Regrettably, he passed away in the spring of 2018. I've enjoyed for many years hiking the California Eastern Sierras, with my wonderful nature-loving wife Terrie. Hence the 'SONORA PASS' title of my graphic novel.
