Ah, I misread that part! Thanks

Up north you could walk down to the lake and jump over the crack and walk to the other side to fish but after awhile that big chunk of ice would move back and forth according to which way the wind was blowing.Sometimes you came back and the crack was now 30 meters wide,so they started dragging a boat across just in case.
Pics in my gallery.

That ice was 8 feet thick and it moved around lots.
