How cold does it have to be and for what duration to get good fishable ice? Is there a formula out there somewhere that you can figure this out? Or does everyone do it like me and just use caution when you go out and drill a hole to check the thickness. I am going to try and go out tomorrow. We have had single digits where i fish for 2 days going into 3. Also, how much does wind affect it? When we have a negative windchill does it speed the freezing process up or just make itr miserable for us. Just curious. Wannabitawerm, let me know what you work the next 3 days. I would love to get out. I am off tues, weds. I bought a shanty and havent even used it. Thats my luck though.
