I fell thru once, I was already out fishing and my buddy was coming to meet me on the ice. I seen him just before he got on where I knew it wasnt safe so I yelled to him to hang on and went over to help him get on where it was safe. I brought my spud and as I hit the ice near where I knew it wasnt safe it broke and I fell in up to just above my waist, I thought I was on the good ice but it all just broke apart and I really didnt know how deep it was, I thought it was maybe knee deep, very ignorant thinking either way Ha I ended up trying to fish with the heater but I was soaked and even tho the crappies were hitting I had to call it a day, this was late february near a dock. Ive also put a leg through near some bubblers trying to find my way of off an unfamiliar lake in the dark during a blizzard, and Ive put a leg through a gass hole that opened up big and twisted my knee. I only count it as going through if its both legs though lol!
