Colm Beattie, 12, right, and his younger sister Avery Beattie, 10, spend some time swimming in the pond and looking for frogs in the creek at the back of their family's 13 acre property in Collingwood after getting home from their last school day of the year, June 27, 2013. Mom, Leslie McIntyre, wants to keep her childrens' summer unstructured, and will allow them to play and explore rather than putting them in organized camps.Peter Power/The Globe and Mail
