Cassidy Popoff gives one last high-five to the sculpture High Five on Columbia Avenue before it was taken down earlier this month. The art pieces from last year’s SculptureWalk (except those that were purchased to remain on public display) have now been removed and organizers are preparing to put up new sculptures for the 2011/12 season. Pat Field of the SculptureWalk board wanted to keep the exact date of the new installations a secret to maintain an element of surprise, but he said you can expect to see them appear in late May.
