There are very few P-38s still airworthy at this time but there is usually one at the static display area. The last one to race regularly was "White Lightning" but it was damaged in a crash landing a few years back and is currently under repair.
There are P-51's galore! Like ten of them racing. There are two gold (top) class P-51 racers, Strega and Voodoo. The world's fastest P-51, Dago Red, retired after last year's race but I wouldn't be surprised to see it back one of these years.
Don't just wish you could be there...BE THERE!!! If not this year, start planning for next year. 3rd weekend of September.
Wish I had the time and funds to do something like that.
