Then, really, it's kind of a continuous exercise. It's not that you'll go for a couple of months and all of a sudden you get two or three calls for service like the fire department does or something like that.
I was interested in the challenge of maintaining some sort of continuity of experience and expertise in the community. People come and go. You'll train somebody up and then they'll leave or they're no longer available. Does that also represent a challenge for your ability to respond?
