Hey hotvedt,
To answer your questions, i like Moses Lake for the work rather than the living/city life. I heard nothing but great things about the facility as far as a place to start out. Is it slow? Relatively yes it is. But there is a great mix of GA (including student pilots), commercial, and military.
I was also told by alot of current controllers and ATMs that both SeaTac and Center like transfers from Moses Lake since people that come from there have a diverse "toolbox", and know how to work traffic, regardless of its level 6 rating.
I met the ATM and the supervisors, and some of the controllers there, and it looks like a great place to learn and work. Remember, most dont stay at one facility forever, so you can always transfer. I really look forward to working there, hopefully when i get my FOL it will confirm so.
