We highly encourage you to sign-up for stand-by, even there are no open slots. Required numbers fluctuate up to an hour before the beginning of a game. We often have last minute changes to work a stand if another volunteer group cannot make an event or if a corporate sponsor adds a picnic.
If you find that you cannot work that stand-by shift, let your volunteer coordinator know before the date. They do not want to waste time calling in people who cannot work.
