A buddy of mine who is a volunteer for CPW was up there today at Kriley teaching an ice fishing class. I didn't hear how thick it was but since it was a CPW event, I'm positive it is great. I will text him and find out for sure and get back but I would plan on fishing it tomorrow.
Edit: he just got back with me and said 8+" on Kriley.
I saw a couple of groups of people on sandpiper this afternoon when I drove by but I didn't personally check it. It would definitely be a good place to take some kids or new people once the ice firms up a bit. You can always call out there and ask how the ice is if there are no current reports here. Good luck.
