What's the thinnest ice you've ever drilled through and fished? Not trying to get someone killed.
Back in 1987 I worked for my uncle in Illinois,he and his BIL co-owned a business.The BIL loved to fish,and I got to go out on the ice quite a few times.One time we went,when the holes were drilled,the ice was only 3" thick.BIL said that was plenty,and we fished,but I was very nervous sitting in that homemade 3-man shanty on 4x4 skids.I just knew we were going to be recovered by divers.
