  The mysterious very high energy gamma-ray source, TeV J2032+4130, is
coincident with the powerful Cygnus OB2 stellar association, though a physical
association between the two remains uncertain. It is possible that the detected
very high energy photons are produced via an overdensity of locally accelerated
cosmic rays impinging on molecular clouds in the source region. In order to
test this hypothesis, we used the Kitt Peak 12m, the Heinrich-Hertz
Submillimeter Telescope (HH-SMT), and the Five College Radio Astronomy
Observatory (FCRAO), to obtain observations in the J=1-->0 and J=2-->1 lines of
both 12CO and 13CO. We report here on the detection of significant molecular
material toward the TeV source region which could be acting as the target of
locally accelerated CRs. We also find evidence of compact molecular clumps,
showing large line widths in the CO spectra, possibly indicative of energetic
processes in this region of Cygnus OB2.
