Yes, it has worked for LB in many ways. It's not easily copied is what my point is. But do know that Pook had Dan Gurney and Les Richter from Riverside Raceway plus a host of others to work on the project. I think J.C. Agajanian helped as well. A lot of lesser known but local figureheads got on board.
Pook, of course, went on to IndyCar as president for awhile. In addition, he was on the Board of Directors of the Los Angeles Organizing Committee for the 2016 Olympic Games. He is a past chairman of the board of both the Long Beach Area Convention & Visitors Bureau and The Greater Long Beach Area Chamber of Commerce, and headed the Long Beach Sea Festival for a time.
He did a lot more, too:
