Under Saturday's blue sky, the fresh colors of spring provided a perfect setting for the town's annual GreenDay celebrations.

Events celebrating the environment and sustainability were planned all weekend across town, ranging from a townwide cleanup of trash and winter debris to open houses at Wakeman Town Farm and Earthplace to a presentation on "Pure House" design hosted by the Westport Library to a documentary on whales, and winding up with an electric car rally.

"Today is all about a celebration of spring for us, especially this year, because we've had such a long winter," said Christy Colasurdo, the co-chairwoman of the Wakeman Town Farm board. "Everything is coming back to life again after a long hibernation."

She credited Michael Aitkenhead, co-steward of the farm, with organizing the first townwide GreenDay two years ago. Beginning as a farm event, it has grown to include nine other local groups.

"It's a perfect day for an event like this," said Aitkenhead, who helped with a range of activities Saturday at the town-owned agri-education property, which included a May pole dance and planting a large tree.

"This is our contribution to the weekend-long event," he said, noting the free food, fun and animal "ambassadors" that inhabit the Cross Highway farm.

"This is my first visit," said Matt Smith of Westport. "It's a beautiful spring day and it's good to be here."

"I'm delighted that in the midst of suburbia we have real rural American, or at least an attempt to bring that back," said Tom Hedberg of Norwalk, who brought his son to see the goats, lambs, ducks and two new alpacas. "I think that's extremely important."

"I like it," said Sophia Mieres, 6, of Norwalk. "I like the goats."

"I come here a lot because I live close," said Brianna Cornfield, 11, of Westport. "I like seeing all the animals and it's always really cool and fun."
