May 19-22 John Muus will be conducting a series of family-friendly free clinics to teach the fundamentals of POP Tennis.  POP Tennis is played on a shorter tennis court with shorter racquets, lower compression balls, and folows the rules of tennis, except no overhead serving.  It is a fun social activity that everyone can play and enjoy immediately.  For more information go to www.playtenniscookcounty.org.  Registration is suggested but not required.  There is no fee for this event.
