Due to COVID-19 and for the purposes of contact tracing, should it become necessary, we desire to limit and carefully manage contact among patrons and staff.  Therefore, if you register for a session in the CRA Lap Swim Program, the lane and time to which you are assigned, are exclusively yours.  You will always swim with and next to the same people.  Your session cannot be shared with or transferred to others.  We are unable to allow any drop-ins at this time.  Thank you for your understanding and support of our efforts to keep everyone safe and healthy!
