Franklin Park Conservatory. I'm familiar with Kennett Square, PA. in a time long, long ago I used to work for CJ Clark Shoes and they had corporate retreats in Kennett Square. Been there a few times.Those are terrific photos.
When I saw the G-scale train it reminded me of Longwood Gardens in Kennett Square, PA and I had to scroll back to the top of your post to see if that was the location of these photos. Nope! Ohio!
What is the name of the conservatory in Ohio? Looks like a nice place to tour.
I absolutely love number 4 - fantastic textures!
