Lets see, the track at Pomona is in the parking lot of the Fairgrounds. And back in the early days, they had to add the grandstands everytime they had a race.
California speedway has been working on their track, they were redoing the surface of the strip last year, when I was out there. They don't use the 1/4 mile part for the parking. They keep the drag strip blocked off durning the other races there. And it can't be that hard to add grandstands and outhouses for some races.
My guess would be that the people in charge of California Speedway know a little bit about what they are doing.
P.S. Tony, where did you hear that they were moving the NHRA winternationals, and finals to California speedway. And when this is happening?
