In Chicago, Illinois, it will be at Hyde Park Art Center, on Thursday, May 3rd, from 3 to 7 pm, and on Friday and Saturday, May 4th and 5th, from 12 to 4 pm. Hyde Park Art Center is at 5020 S. Cornell Avenue in Chicago.
A note about the old Gliderport: both it and the old warehouses near it, which you can see in my blog post, The Sketchbook Project - I, are slated for demolition, likely to be replaced by a luxury hotel. They are treasured parts of a part of Calistoga's history, and I'm very glad they will at least live on in these sketches, long after the wonderful old, funky buildings themselves are gone.
