Random walk in random environment is a model for motion through a disordered medium. Traditionally this is studied with fairly strong non-degeneracy conditions on the environment. I'll describe some results in which those conditions are relaxed, which leads naturally to questions about percolation on random directed graphs. I'll also contrast this to the standard theory of percolation on the square lattice. This is joint work with Mark Holmes (Auckland).
