My first flying job was ag work - but I didn't just walk into it off
the streets, I'd been working for that operator as a combination
loader/truck driver/A&P mechanic for over a year. As a matter of fact,
that's how I built up the flight time to get my CPL in the first place
- I had just over 40 hours when I got my PPL, started ferrying
helicopters between job sites to build time.

It took a year or so to get 150 hours TT, even considering how crappy
the pay was I still came out ahead. Plus I had that first job lined up
too - in my case having the A&P license already was a huge help in
getting in the door...

I'm not in the ag business anymore, not even in aviation for that
matter - I miss the flying, but not the pay.
