Many Yellowstone Park travelers prefer to travel with special parties of
congenial people under the popular all-expense plan. These tours will be
operated during the Yellowstone Park season and those desiring to join
one of the parties should call on any of the Chicago, Milwaukee, St.
Paul and Pacific Railroad travel bureaus shown on the inside back cover
of this booklet or write direct to Mr. H. Sengstacken, Passenger Traffic
Manager, The Milwaukee Road, Union Station, Chicago 6, Ill.
