From "The Rise of the Biggest Little City" by Dwayne Kling:

Merry-Go-Round Bar
"26 West Second Street; licensed from March 1946 to August 1956 for slots, craps, 21, and roulette.

The Merry-Go-Round Bar was located the the former site of Blondy's Bar. The bar was actually set on a carousel mechanism that when activated caused the bar stools to revolve around the center part of the bar."

...
...(mainly names and dates here, and I'm not typing them...also mentioned is that the last licensee was Lonnie Logsdon, who was cited for improper operation of a 21 game)
...

"On July 31, 1956, The Gaming Control Board recommended revocation of the slot and gaming license, and on August 1, 1956, the State Gaming Commission concurred.

The former location of the Merry-Go-Round Bar is now part of the Pioneer Gift Shop."
