  We couple c=-2 matter to 2-dimensional gravity within the framework of
dynamical triangulations. We use a very fast algorithm, special to the c=-2
case, in order to test scaling of correlation functions defined in terms of
geodesic distance and we determine the fractal dimension d_H with high
accuracy. We find d_H=3.58(4), consistent with a prediction coming from the
study of diffusion in the context of Liouville theory, and that the quantum
space-time possesses the same fractal properties at all distance scales
similarly to the case of pure gravity.
