From 70 to 81 I would not play in any 3C tournaments because NO substantial money in them! Even the 3C Nationals offered none in comparison to what I made going across country gambling. During those years I accumulated a nice BR, and invested fairly well. My mentor wanted to travel to events in his last years and so we did. Since the money/prize fund was not an issue anymore, I did begin to play in US/World sanctioned tournaments. I have to be honest, in comparison to economy, inflation, in USA monies have Not increased by 15% through out All these years. For "ME" it was Always about the cheese!
IMO, for the 'Older/Hardcore players' this event is about, 'Bragging rights' that group will attend regardless. For the, '55 & under' group that may still be working/raising families, getting a pay day will offset their expenses.
