Similar, in some aspects to the USFS trail crew, I was on an Interagency Hotshot Crew for five fire seasons. Working in tight quarters with 19 other like-minded people. Working 14 days straight, 12-hour days, 16 average, then two days off at home...repeat for five months or so. Make a pretty good wage with about 1000hrs of overtime in that five month period, with no time to spend it. Then get 6-7 months off, paid by unemployment (for a hotshot crew = $500+/wk). Spend that time off travelling the world. Just about the time you run out of funds, its time to go back to work. Wouldnt trade those fire seasons/off seasons for anything. Pretty hard on the body though, so not many folks can do it forever.
