With WMI you also get the awesome NOLS graduate newsletter THE LEADER so you know you are super rad. I tape mine to my window for all to admire.
Also note that if you want classes tailored to the working man, many community colleges can teach the EMT-B courses in the evening over the course of two semesters. The EMT-B is a similar level of medical training but is of course geared to an urban setting where definitive medical care is under 1 hour away. If you ever get into "professional" rescue you will find the EMT-B means a lot more to the state than some random WFR cert, even a WMI cert. The WFR will certainly serve you better in le backcountrie however.
