If you are lucky enough to be in a campground like Algonquin Park in Ontario, then you can pick fresh blueberries. These are the best for Blueberry Pancakes.
Just go out early in the morning with a little bowl and basket and pick a bunch. Wash them off and then add them to the pancake batter.
Cook them on the griddle on the Coleman stove and you have the best camping pancakes you'll ever taste.
