career options for a physics grad

hello,

I'm a physics and mathematics graduate looking for some career advice.
I took first year engineering, some chemistry a few computer science
and then a whole lot of physics and math courses.

I'd like to know what people with careers in Programming, Engineering,
and Geophysics/Geology careers think of my career options.

I want to advance toward a career, but I'm undecided about what direction
to head. Like most people I want to eventually have a career which will
give me a certain amount of security and a reasonably comfortable income.
I have a job (data processing) under several P.Geo's. Also, I'm taking
programming courses on the side. Here are some of the options I've
considered.

1. Continue to take programming courses and hopefully get
a job Programming.

2. Pick up some Geophysics courses and try to get a P.Geo.

3. Go to grad school for Geophysics.

4. Go to grad school for Engineering such as Mechanical Engineering.

An ideal career for me would be one that would use as much of
what I've already studied I'd like to spend as little time as possible
taking supplementary undergraduate courses. With this in mind,
I'm leaning toward Geophysics. I feel this is an applied physics
whereas engineering would require learning something completely different.

My final question is which is more valuable in industry: a P.Geo. or an MSc.
in
Geophysics?

thanks for your time,

Ryan
