I’ve seen roughnecks (shout-out to Odessa!) spray painting it on to gas-station foam coolers. Those wacky oil guys.
(But, seriously, leave the bar when the seismic boys show up. Seriously!)
We have a geologist who comes in where I work. He looks like the most burned out individual on God's green earth, but he's got a masters from Colorado School of Mines. I don't even have to ask, I already know he's got to be a seismologist. No question. (ed. note I worked as as a doodlebugger for a little while in my younger days).
