Longest continually running dragstrip in the US

In Pomona it is 88 degrees and no shade. The stands are aluminum and really heat up in the sun. Lots of people are traveling to other places before school opens up in a few weeks. NHRA is trying to get the Winternationals done in the summer and so they are running the big boys ($$) later in the day in order to have the flame throwing nitro cars run their finals in the dark like in the old days. I am watching it on a local channel here and only one side of the stands have spectators widely dispersed. I wouldn’t call it a crowd either.
