http://www.seedstogreens.ca . Its a lovely retired couple who decided to start a little farm. They are located close to the Calgary Corn maze in the Deep se of calgary. I know they relish any kind of volunteer help with weeding as it is all organic and a lot of work. They also won't hesitate to educate you or your little ones on farming know-how.
Their strawberries were delicious, and well priced for being hail-damaged, perfect for smoothies.
