Oil from cars I believe

IBERnineD is correct.

Yes!!!

@johnpowell is correct about @IBERnineD being correct.

@Zen You nailed it! GA for you!

And people need to get the gasket on their oil pans checked. That oil eventually ends up in the drainage that goes into rivers. I’m pretty sure that pisses the fish off. And you don’t want to make the fish angry. and I like to eat fish

You mean other people see that, too? Here, I thought it only happened to me and was caused by me tracking baby oil out of my house, where it is used in abundance (and we have no babies, by the way). Guess I learned something new today, after all….I sure love fluther.
See ya….Gary/wtf

When it’s dry and hot, I see all kinds of things on the road up ahead in the distance… I hate that fata morgana…

Oil from cars and from the tar itself , causes the magic rainbow colours .
I like seeing the steam rise when it rains on the roads / pavements
