  1. Log "WILL ATTEND" on this event page. 

  2. Register through the City of Richland's Parks and Recreation page: REGISTER HERE.  Yes, this step is new and very important! This is how we will keep track of our numbers, know how many coins to purchase, and have the ability to communicate with you all regarding any changes we have to make due to COVID, etc.
    If there is one thing we all learned this past year, is how to adapt to constant change.  wink
