  A detailed analysis of Monte Carlo data on the two-dimensional Ising spin
glass with bimodal interactions shows that the free energy of the model has a
nontrivial scaling. In particular, we show by studying the correlation length
that much larger system sizes and lower temperatures are required to see the
true critical behavior of the model in the thermodynamic limit. Our results
agree with data by Lukic et al. in that the degenerate ground state is
separated from the first excited state by an energy gap of 2J.
