Bellfest,
When does one decide the ice is too thin to walk on? I guess we all have our own standard....some like to jump up and down and feel no give...some will bore a hole and measure the thickness...some will creep out listening to the creaking and groaning of the ice...some will weigh the sinking and giving of the ice....before they turn back for shore.
If you don't mind the creaking and groaning....the sinking of the ice...and being able to see the fish swimming around under your feet....fair dinkum.
Me...I will keep my reasonably intact hide on the shore and watch all you other guys ice skating thank you.
