The Ecotarium was very much "it was the best of times, it was the worst of times" sort of place. No mater when you worked there or for how long.
I was only there for 2 years in college. My wife was there for almost 10. Our other friend for about 20. There was a lot that was fun there, but it took it out of you in other ways.

We are thinking of a trip to the Cloisters later this year. Not sure when, but you'd certainly be welcome to meet up with us there if you wanted.
