Yes, well, there seems to be at least four or five vintages of asphalt at Pomona (some of it relaid, some of it just sealed). You can see them on the satellite photo:

The newest asphalt is on the DE course, even though there are a couple of fairly deep dips, one coming out of the first corner behind the dragstrip grandstands, on one right before the telephone pole you mentioned. (The guys with lowered suspensions and stiff springs really didn't like the big dips, especially with 150-200 lbs of balast in the right seat). There are some course options off this asphalt, but they are mostly near the big sweeper at the north end, and a few in the middle part where the L/R/R/L chicane is. This is mostly second to newest asphalt, and it is slightly lighter in color (and is starting to break up, at least coming out of the chicane). The north end of the parking lot where we pitted looks like the third newest, with a lot of cracks everywhere. The oldest of the asphalt (in various spots, including the inside of the DE course) is really old and crunchy and very light-colored, like all the tar is gone; it's like driving on the moon, only with slightly less dust. I guess every old venue has its issues...
