Well , I have been going to Eldora since the early seventies.There has always been some dust. My opinion is that that the issues with dust as we have it now started with some bad dirt being put on the track and then they built the suites. I think that the suites block a lot of the air that used to "ventilate" the dust somewhat.Just one guys opinion here. Time always has a way of making things better than they actually were. peace
