   W: Hello, Everyone. Welcome to the annual company picnic. We're here today with our coworkers and our families to enjoy a day of sun and fun. Before I tell you about today's festivities, I'd just like to remind you of a few park regulations to make sure that our day is pleasant and entertaining for all. Please remember that this is a non-alcohol event. City ordinances prohibit the drinking of alcohol anywhere in the park area. We'd also like to remind everyone to please throw your recyclables away in the recycling containers located near the park clubhouse. Recyclables are any item such as glass bottles, aluminum and metal cans, and plastic food containers. All other garbage should be thrown away in appropriate trash cans located throughout the park ground. Thanks in advance, everyone, for picking up after yourselves and keeping our park clean and beautiful! Have fun!
