You are incorret when it comes to the firedepartment.  Being at work for 24 hrs 7 days a month....let me restate those numbers.....AT work and  NOT working 24hr 7 days because I do not include sleeping and eating well and watching the Leafs of TV working.   At work but not working.  Most Firepeople have jobs outside of their parttime 100K job as they have so much time to kill.  If you need plumbing, deck work, painting, car repairs, general renovations, snow removal, landscaping there are plenty to choose from.  From 20 to 40 bucks an hour....ALL cash, so basically thumbing their nose at their employer.  So when including the fireboys and girls I would add an additional 30K at least in gross income.....maybe even net income!!
