I suppose any blog should identify the writer as the first order of business.
I'm a Mormon, a research geophysicist with the US Geological Survey, and a Jujitsu Sensei. I'm married to an amazing lady who gave me the five most eclectic kids on Earth - all of whom I'm extremely proud of. In my family we count fluency in Spanish, French, Arabic, Mandarin, Czech, Slovak, and some Russian.
