I'm looking for info on a temporary circuit at the "Austin Fairgrounds", which may correspond to the "River City Road Course" referred to in America's Speedways that ran at the Texas Expo and Heritage Center from 1977-1980. Details, course maps, etc., much appreciated. Update
Of course, if I were paying attention I'd have noticed that there were two street courses in Austin, one at the Fairgrounds and one at the Convention center. So I need to sort this out. Again, any help is greatly appreciated.
