That's the biggest one I found. Brown County State Park Indiana. In the area of the campgrounds. I don't hesitate telling where I find them, I'm quite sure for every one I find,, thousands go unnoticed.
Many decades ago a couple friends would drive into Michigan and find them by the basketfull. They usually brought home the pickup bed full of baskets. They had a way of canning them in recycled pickle jars; they wouldn't share that secret.
jackiemac, that looks like about 3 good meals for two. Bacon N eggs N mushrooms, YUM!
I don't pick the round smooth ones; however I do pick elephant ears when found. They are not as good as morels though IMO.
