I am in northern lake county Indiana (right next to cook county). I picked 51 big yellows Thurs. And 10 more even bigger ones Fri morning. Some were starting to dry out , and some were very fresh. I was hoping with the rain we got Friday evening, that a few more would pop up. I am going this evening to check....so as of Friday morning I was still finding them, but the size alone tells me the season is just about over.
