'Ohio's Garden Path'
The Ohio Historical Society in Columbus has a new exhibit opening in April called Ohio's Garden Path: the Flowering of Our Landscape. Sounds pretty cool; it is divided into eight sections, including immigration and Settlement, the Romantic Revival, the Country Estate Era, and the Modern Movement.
Looks like fun if you're around Columbus. It opens Apriul 2nd, but there are associated events scheduled thru November. I've already put a note on my calender for September, a talk on architecture and landscape.
Hope this link works for you.
