Southern California - no place to drag race in the birthplace of drag racing

The ground under Irwindale is just one giant sand wash :lol: Being so close to the mountains that sand is also occupied by some rather large chunks of aggregate that just rolled with the flow :lol: They have numerous neighbors that specialize in the processing of such material for their use in concrete and asphalt products. I attended the "Last Blast" at the previous Irwindale in the late 70s. Many racers that evening expressed their displeasure with "MILLER BEER SUCKS!" added to their race car graphics :rofl: Few years later their sits a Miller brewery.
You have first hand knowledge and in my opinion that’s much more solid than hearsay. But, what you say is in the ground there, and what I heard is in the ground there are complete polar opposites with regards to natural or unnatural things. I’ll leave it at that.
