The school complex has a pool and a skating rink that is shared with the community and surrounding areas. Admission to rink is discounted to Town residents, and is used by many from surrounding areas. Very nice friendly community center feel to it. I have also seen this type of arrangement in towns in other states, Massachusetts, Illinois, and California.
Where I grew up the cluster of three schools (elementary, middle, and high) had the pool at the middle school. It was open to the public evenings and weekends during the school year. Plenty of lakes to swim in during the summer - but used for ice fishing in the winter!
