That could only be on the roadway, if someone wanted it there.

Maybe with one of the tankers and an open valve?

Where would they get enough of the seeds to treat and
have the amount needed to ruin a roadway?

I can see why the road is closed, the tires would throw it into the air........

Good work, this find.

Hmmmmm.

Is there any new info on the 'waxy substance'?
