The buildings still exist. The showbar is now a mattress store. The pract. room in the back looks to have had a upper floor added. The Jansco's Stardust golf course is just south a tad and is still open. https://email@example.com...4!1sOvnKyPlveY6sHqR-NLHZRw!2e0!7i16384!8i8192I went to JC four years in a row from 1964-67. The tournament was held in a meeting room in the Show Bar, where they had seating for about 200 people, which was adequate for the tournament crowd. There were only two tournament tables with bleacher seating around three sides. Tickets to watch the matches cost two or three dollars. The "practice room" was where all the action took place. It was in a separate building just behind the Show Bar. They usually charged a small admission to get in there as well, maybe a dollar or two. There were two rooms. The front room had three tables and bleachers on one side that maybe would seat 50-60 people. Everyone else stood along the wall all the way around the room. The back room had two more tables and also had some bleacher seating. People lined the walls in here too. The crowds were so thick with people that it was difficult just to work your way through to get from one room to the other. If you could find a bleacher seat you were wise to keep it.
The big money games ($500-1,000 bets) usually took place in the front room and the nightly Ring Ten Ball game ($20-50 a man) was in the back room. I spent many nights weaving my way from one room to the other watching the best players on the planet battle it out for supremacy. I took it all in and always felt bad when I had to leave after a week or so because my money had run out. JC lasted three weeks and the longest I was ever able to stay may have been ten days.
