The meeting place became known as Conference House, and is now a NYC park.
We went with our SI friend - stopped for deli sandwiches on the way, walked around the grounds a bit, picnicked, and relaxed!
Here's the Conference House
You can see the New Jersey shore from the bottom of the lawn
This is the Biddle house
With interesting benches
Further out on the bluff is the Rutan-Beckett house
The backyard view
And the backyard view :-)
(This entire flower is no bigger than the tip of my pinkie)
Where is it?
