Its sad, but I think its a function of the economy and particularly the pool economy in general. 15 years ago when the pool rooms were all filled, everywhere, Barry had a ton of income from his rooms to support the event. Now, that pool is dying a slow death, rooms are closing left and right, and remaining rooms are doing less than half the business they were 15 years ago, he doesn't have the cash to pay the US Open. I don't think the US Open was EVER self sustaining. It always relied on Barry's multiple pool rooms to support it.
Disclaimer, the above is my educated guess of 2 cents.
Best.
It is a very good guess though.
I went to the open in 99-01, and pool was by far better back then. Way more action everywhere. Now there seems to be none, and the new kids on the block don't gamble like they did then.
