What's being a taxpayer got to do with it? It's not like being a taxpayer gives you all unimpeded rights and privileges to a whole state. You can only go to parks at certain times, only go to the library at certain times, or city hall at certain times. Universities, even public ones, are even more impeded In terms of access.
Anyway, to the original poster. Generally, you can get onto the track to see it but most of the time the big swinging gates are blocking lanes 1-5/6. Lots of different groups do run on it, and I there were some public hours but I've never bothered looking into it as I train on other tracks in the area.
