Memorial Day weekend, May 25-27, marks the summer opening of Spring Lake Regional Park's swimming lagoon, floating Water Park and kayak and paddleboard rentals. Part playground and part obstacle course, the inflatable, floating Water Park is for kids (at least 6 years old and 42 inches tall) and adults who like to make a splash – and a hop, flip and a jump! Tickets are $10 for a two-hour session, and reservations are encouraged.
