I work on the rigs for a oilfield services company. My official job title is a "measurement while drilling field service engineer". The job would take way too much of my time to explain so if you care here is a link about it http://en.wikipedia.org/wiki/Measurement_While_Drilling
In my off time--I consult to oilfield companys on health and safety practices and procedures.
I am a bulk delivery driver for Pepsi Bottling Group. I run, obviously, soda from Riverside, Ca. to grocery stores in 29 Palms, Yucca Valley, Palm Desert, Rancho Mirage, Palm Springs, Cathedral City, Indio, Bermuda Dunes, Desert Hot Springs, Mecca, Blythe, and so on.
