Well, happy birthday. It sounds like you have a nice place to retire up there.

I never much liked my birthday. Just mailed a card and package to 2 upcoming birthdays...a 50 and a 40...a best friend and my brother.

I'm a geologist with only 1 geophysics class, some remedial math and a single calculus as an undergrad. But, I got a job as a "geophysicist" with an oil company: they were hiring geologists to interpret seismic reflection data...because interpreting 2D seismic is an art and the physicists were no freaking good at it. We called ourselves "pseudo-geophysicists".
I was actually good at this and they liked me at Gulf Oil.
Later, in grad school and summer school before grad school, I took 7 additional math courses. What a total stressful waste of time that was for me. I learned to do the problems but had not the tiniest understanding of them, so then entirely forgot it all. I now make good use of simple algebra and trig.

Another story about the good old days...Tom Dibblee gave a talk at the monthly Coast meeting in Ventura a decade ago and talked about doing field mapping (back in the 30s?) in the area of Ventura basin...there was a geologist in every canyon and when out mapping they would keep encountering each other.
