I've always thought it was really neat to be able to fix things when things went really wrong.
Perhaps it all started while watching the 1970s NBC television series Emergency! when I was a kid. I got into hiking and camping when I was 14, and I was always into being prepared for wilderness emergencies. I've been certified in First Aid and CPR more-or-less continuously since my teens. I was a hospital volunteer for a while, and even considered a career in emergency medicine at one point.
By the way, because I was such a fan of Emergency!, which was a show about the Los Angeles County Fire Department's paramedic program, it was a great treat for me to be able to visit the County of Los Angeles Fire Museum during their open house in June 2008. I was also able to visit a couple of shooting locations during the same trip. My photos of that visit are posted on Flickr.
