  We explore the relationship between exclusive and inclusive electromagnetic
scattering from the pion, focusing on the transition region at intermediate
Q^2. Combining Drell-Yan data on the leading twist quark distribution in the
pion with a model for the resonance region at large x, we calculate QCD moments
of the pion structure function over a range of Q^2, and quantify the role of
higher twist corrections. Using a parameterization of the pion elastic form
factor and phenomenological models for the pi -> rho transition form factor, we
further test the extent to which local duality may be valid for the pion.
