Outdoor Airsoft events happen every second week on Sunday afternoon or evening from March to the end of October. The events are open to the public and the vast majority of the players bring their own gear and simply pay a basic field fee. The events are organized and Merrill Dunes provides a director to coordinate games. Around the middle of July there is a large scale Mega Game that is a highlight of the year. There are several video productions available on this website showing the activity during mega games in past years.
