I present exhibit A! Found this picture on social media. Zoom in and you’ll definitely see the pebbles/rocks. Regardless of the rocks, it looks like a neat track from watching flo. Can’t wait to check it out in person

I was never under the stands when cars were running, so I didn't experience the sound of rocks hitting. I guess we just picked the right place to sit to avoid the rocks.
The track needs more signage to direct spectators to the correct gates. It is a problem for first-time visitors. As I said previously, I have mostly positive thoughts about Circle City.

I sat right behind the flag stand about 7 rows up and there were rocks all night long. Going to a dirt race, I expect to be hit by something throughout the night.

For the Allstars race, I sat closer to turn one about 7 rows up and there weren't rocks.
