If you want to fly and forget the job on scheduled days off-the Gulf of Mexico.. .If you want more involvement and work in your hometown-EMS.
Average annual flight time for a "Day VFR cog in the Gulf of Mexico machine": 3-400 hours. Lots of jobs fly 4-6 hours a day and some do 8 hours day in and day out.. .EMS seem to fly a lot less. Not a universal rule.
You can fly crap in EMS or oil patch. Or you can refuse and insist on airworthy aircraft. Greatest favor somebody who won't fix the aircraft can do me-hassle me off the job. I think the expression is "I was looking for work when I came here, so I haven't lost anything leaving..."
