“I did not realize that I was to meet you today, still less to address an audience such as this; and I had only come prepared to go into the Yosemite with John Muir; so I must ask you to excuse my costume. (Cries of “It is all right!”) I have enjoyed so much seeing southern California and San Francisco that I felt my trip would be incomplete if I did not get up into your beautiful country and then see the Yosemite.” From "Remarks of President Roosevelt at Raymond, California, May 15, 1903."
