§ 211. Fair association, when entitled to privileges. Any state, county or other fair association shall be entitled to the privileges conferred by section two hundred four of this article upon filing in the offices wherein its certificate of incorporation is filed, a certificate that sets forth its intention to avail itself of such privileges; and any such state, county or other fair association shall not be required to obtain any license or file any other certificate. State, county and other fair associations entitled to conduct trotting races may also conduct running races in connection therewith, and the provisions of this article requiring a racetrack to be of specified dimensions shall not apply to such association; but no running races shall be conducted for more than five days on any track or grounds, unless the license of the commission therefor is first obtained.
