Anyone been to New York Botanical Gardens??

No, I have not; but judging by their website, I'd try and fit it in my schedule. Always fun to see some plants in indoor tropical settings that we routinely grow here in Florida - plus a whole lot of other stuff that we cannot grow. There's the Brooklyn BG also.
I have many times. It's certainly worth the subway ride which puts you out directly at the gate. If you go on an especially good fall or spring day, it's magnificent. Try to work it into your schedule.
