how often do you change your spark plug??

I just changed mine in the Grizzly 660, it has 500 miles. I went out yesterday to clean the driveway after the snow we had Sunday nite, and for the life of me I could not get the the thing to start. Put a new plug in and fired right up, not sure why the other plug went bad so easy. It ran great when I parked it Friday. Plan on keeping one or two on extra, who knows where the next on will go out.
