  High quality polarized electron beams at Jefferson Lab make possible
precision measurements of hadronic properties in the regime of strongly
interacting QCD. We will describe a few programs at Jefferson Lab that are
making measurements that link the basic static properties of hadrons to their
quark sub-structure. For example, parity-violating electron proton elastic
scattering probes the spatial distribution of strange quarks in the nucleon.
The nucleon-Delta transition form factors give us information about the
deformation of nucleons and Deltas. Finally, new high statistics measurements
of photons scattering off proton and deuteron targets are used to set upper
limits on the production of exotic baryons with strangeness S=+1. These
examples will be used to illustrate the capabilities and focus of the
experimental program at JLab.
