I live within 70 miles of Shadehill and fish it in the summer. I have asked about ice fishing there but have not got any response either. Either the ice fishing is no good or it is so good no one is talking !!
The phone # to the store is 605-374-5535. They may be open this late, I am not sure. It was still open the weekend after Thanksgiving.
Let me know if you get any info.
