(a) Any county or county board may operate a program of public recreation and playgrounds independently; or they may cooperate in its conduct and in any manner in which they may mutually agree, including with cities, towns, or school districts; or they may delegate the cooperation of the program to a recreation board created by one or more of them and appropriate money voted for this purpose to the board.
(b) In the case of school districts, the right to enter into such agreements with any other public corporation, board, or body or the right to delegate power to a board for operating a program of recreation shall be authorized only by a majority vote cast at an annual school election.
