I think that California has made great improvements in their smog situation over the years...I am not a
big fan of pollution controls on motors but in 1971 you couldn't see a car cross the finish line when you
were standing at the starting line at the drag strip in Pomona. Now, you can see completely across the
parking lot....mucho better. Of course, now there are many times more cars AND not all pollution is
from cars. I think they are at the point of diminishing returns now, the easy stuff has been fixed.
