Any windmill techs here?

I'm tired of ridding the unpredictable lows of my job. So I've been job hunting.

I got offered a position as a turbine technician by GE. The job description says I will be in charge of a certain area so my drive time is pretty much set which I like.

Can anybody share their experience in that field? Both good and bad. And more importantly whats the room for growth like if any? I'm teachable and drive towards learning anything that pertains to any job I do no matter how big or small. I always carry a tally book with me to jot down notes and advice when I'm in the field.
