There were a number of bars in Houston that also operated just outside the Montrose neighborhood.
The Pink Ekephant opened in 1936 and was Houston's "oldest and friendliest bar in Texas." It achieved a national level of notoriety through its presence in the 1952 book USA Confidential by Mortimer and Lee, where it was among a handful of businesses noted for catering to the homosexual set. The Pink Elephant has been associated with many operators, perhaps most famously “Miss Effie” (James Sears) and later, Bill Smith.
"The Pink Elephant's forty year stretch gives us a vivid example of the evolution of the gay bar, from the days when it existed for the sole survival of gay society until today when they exist for numerous purposes (cruising, socializing, drinking, dancing." --Charles Casey, "The Bars: A Vital Center of Gay Lifestyles,: 1980
The Galleon was a nautical themed bar that operated in two locations on Richmond from 1968 until 1989. It was operated by Jay Allen when it relocated and was the founding sponsor of the Montrose Softball League.
The Briar Patch was a long-time Houston bar that operated from September of 1970 until the spring of 2005. It was known for its piano bar atmosphere and older crowd.
Formerly The Spurr and Adams Image, the Brazos River Bottom opened at 2400 Brazos in 1978 and was in operation until March of 2013.
Issues of TWIT also featured ads for other bars and businesses throughout the state of Texas, including Robert's LaFitte in Galveston, which is still in operation today.
