The Holden Arboretum has added a new exhibit for the 2007 season in the form
of a garden-scale railroad. Bridges and structures along the route are artistic
representations of the same ones that exist around Northeast Ohio, and the entire
display involves more than 2000 linear feet of trackage in a space of about 50' X 80'.
The trains weren't running when I came, but I'll be making an album of images to show
more of this fascinating miniature world after I also have some "action" photos.
