I tested at OSW in the Late Model today. Thanks to a tip from my friend Brent I did an “extra special” track sweep before going out there.
This was the “leftovers” from yesterday’s practice 
looks to me like you missed quite a bit
or they got most of it already
every track i have ever walked you find several hand fulls of stuff like that
That was just from the main groove. I didn’t go near the high line in the turns!
