The installation has been up for nearly two months. Of course, I've been running around so much that I haven't had time to stop and check it out. Until yesterday, that is.
If you have never been to the Marietta Museum of Art, is it just south of the Marietta Square. I find the easiest route is to start south of Marietta and travel north on Atlanta Road, which becomes Atlanta Street, which becomes Cherokee Street north of the Square. As you approach downtown Marietta, Atlanta Street becomes a one-way street. Get in the new left lane, go a scant half-block, and park next to the big white classical building (which is the museum). If you are coming from the north, either circle around so you can drive up Atlanta Street, or park on the square and walk down from the southeast corner. If you are looking at Google Maps, do not be misled -- the Marietta Museum of History is not the Marietta Museum of Art!
There are lots more details to see in person, including four more columns, another porch rail, and lots of swags on the ceiling.
