 The park also has facilities for tennis, softball, swimming, track, croquet, volleyball, skating, cycling, and a running course ().Very popular with Houston joggers, the running course is the Seymour Lieberman Exercise Trail, a crushed granite pathway that sees almost 3 million visits annually.For joggers used to running in the lush green surroundings it is disappointing to see the shrinkage in the number of trees as a result of drought and hurricanes.
