I read the article entitled "A-maze the kids" in the Ottawa Citizen (1999-01-22). I would like to point out that I have designed a built ice and snow structures for several years. This year, I have the following structures in my suburban single family home.
Front Yard
a maze
toboggan hill
Back Yard
a skating rink
an igloo
Also, there are 2 HyperFeeders (pole mount and overhead mount) in the back yard. Besides house sparrows, the HyperFeeders attract blue jays, cardinals and chickadees every day.
The size of the property is 16.02 metre (52.56') * 30.43 metre (99.84'). You are welcome to visit and take photographs of the structures before they melt away.
