Sadly there weren't many people there to enjoy it. It was quite cool. Had a few stalls with lots of helpful enviro stuff, a few stalls about cleaning the cooks river and surrounds including information about sightings of long-nosed bandicoots in the GreenWay corridor (Iron Cove to Cooks River) that I just had no idea about. There was plenty of kids entertainment including theatre and stilt walkers, workshops for the grown-ups, and also a UNSW demo of a solar powered Wii.
We did get to eat some tasty food. I had a kafta roll and an iced lime juice. We also got some goodies like a shower timer and an LED touch light.
The river around Ewen park looks like this:
