I love it because I can make a difference.....that others don't care enough to do....It also sets me apart from the world and helps me to connect with people that have enough room for emotions that are for more than just themselves.....
The family type atmosphere, brotherhood, and just knowing you are doing a good thing for the community you live or work in.
Also my mother told me when I was a little boy running around at the engine house that if you like what your doing and your good at it THRIVE ON IT!
