I first read it seven years ago and similar to the author, it inspired me to join my local Search & Rescue team which has been incredibly rewarding. I highly recommend doing that to anyone who wants to combine a love of the outdoors, specialized skills, serving the community, and helping people in their worst moments. (And doesn't mind getting up at 3am in pouring rain and going out and pushing through dense underbrush for hours!)

If any power company has the ability, much less the inclination, to not charge you for your appliances waste heat that would be news to me.
