done, slapped some of this ol contact cement all over and into the crack, let it dry then put a bunch of black hockey tape on it. I had repaired at the beginning of the winter but kicked it a bit too hard on -25c day, so had to redo it. Looks like it will hold, just have to remember not to push too hard with my boot when pushing into a big hard pile.

If this goes again, I think I will glue some old tube material onto it and then take a butane torch to it to melt it all together into a nice gooey mess that should harden up well when cooled. The contact cement should make a good flame --What can I say, the kid pyro in me is still there I guess...
