When I lived in BC or visited the island we would go mushroom picking all the time, normally for morels and oysters, sometimes we'd get lucky and find psilocybin..
We would also pick black berries, salmon berries and wild strawberries. Sometimes we'd go for Shellfish - mussels, oysters, clams and crabs...
Here is AB I've picked apples, mushroom rings, saskatoon berries, raspberries and huckleberries. I've made wine out of foraged dandelion roots. I also love making horse radish found on old homestead properties.
I remember listening to a radio show once on foraging in NYC. It was really interesting all the plants that grew wild in the concrete jungle. Apparently they do tours of the city..
