Dear Mr. Gray, Though I could be mistaken, as I haven't lived in Chicago for nearly seven years now, I'm pretty sure you were wrong when you said Grant Park was the "Hundreds of acres of prime lakefront real estate, set aside for public use since 1835" [“TCB,” Music, July 29]. Grant Park, at least as far as I knew, usually referred to the comparatively small area surrounding Buckingham Fountain, between Michigan Avenue and Lake Shore Drive. Thus, the Art Institute – though close to the park – is not actually “in” the park.
