The Vernon Arena, located just south of downtown Los Angeles, California, was a major early 20th-century west coast of the United States boxing venue.

[17] According to Los Angeles historian Cecilia Rasmussen, Doyle's first venture in Vernon was "a gigantic saloon, where 37 bartenders rang up liquor sales on 37 cash registers at a 100-foot-long bar.

"[18] Doyle's bar closed in 1919 due to the national prohibition on the sale of alcohol,[18] but he had already set up a training camp that was located out back, past the card room.

[19] A show-business history published 1934 stated, "All the big fighters of the day, as well as preliminary boys, has-beens, and hope-to-bes, trained at Jack Doyle's camp.

"[20] According to boxer-actor-trainer Dewitt Van Court, "The camp was patronized by the finest boxers in the land and their popularity drew such huge crowds, particularly on Sundays, that Doyle had to erect a regular arena and surround it with stands which would accommodate several hundred people.

[30] In the interim between the passage of Prop 7 and January 13, 1925, the date of the first fight under the new law, a planned 10-round bout between Jimmy McLarnin and Fidel LaBarba, Doyle added another 2,000 seats to the coliseum.

[31] The fire started in a neighboring "sawdust and shavings" mill, and also destroyed the grandstand of the Maier Park stadium where the Vernon Tigers had once played baseball.
