On the Blunders and Beauties walk, hosted by Jack Hanna, hear about boo-boos made by builders and bureaucrats; the geological history of Centretown; the story of the Nature Museum; and notable historic personages.

The walk covers about one kilometre and takes about an hour.

Meet at the Elgin Street Market at the corner Elgin and Waverley at 11 a.m.

There is no cost, but a donation to the Centretown Community Association is appreciated.
