But there are several reasons for it.
1. Some tracks either oiled the dirt or used calcium chloride. It helped quite a bit. Tougher environmental laws now forbid doing that.
2. Aaa or usac shows had maybe 15 - 20 cars at a race with pretty narrow tires. Qualifying, dash, heats and a 12 car feature. And that was it. No 4 or 5 support class stuff.
That made for some pretty racy dirt surfaces even in the daytime. One would ocassionaly get dry/slick, but not that often.
the tires dug in! Not wheel pack the track like the steam rollers!
