I ran a small club during it hay day we played 5 times a week, I also taught adults education, rented myself at tournaments. I made a nice second income for 28 years but as I said a small club. Friends of mine had a club that ran 6-8 times a week with 3-4 sections of 12+ tables, gave both groups and private lessons, rented themselves out at tournaments. Husband also was an ACBL NATIONAL DIRECTOR. They made a very nice living for years. Not all clubs make money, RENTS are killers, also Insurance. Now the large drop in attendance do to aging population. I closed my club about 5 years ago. Someone else tried to take it over but isn't drawing players. Personality and the ability of running one properly is also a major issue.
