No need to sign up. This event is for all skill levels. Arrive at 6:00pm to the lower tennis courts with or without a partner and jump right in. This event is designed to be social and teams are continually rotated in a casual round robin style.
For absolute beginners, there is usually one court dedicated to the introduction of the rules.
This activity is weather permitting, but will usually run unless it is actively raining.
You can sign up to be included on an email list to be notified if Drop-in play is cancelled due to weather, but it is not necessary to join.
