  In any given 24-hour period, the Fermi-LAT detects photons with energies of
order 100 GeV not associated with any known VHE emitter. The RA/Dec of these
photons frequently falls into the field of view of VERITAS the following
evening. A single photon in the LAT can potentially mean many detectable
photons on the ground due to the superior collection area of the IACT (Imaging
Atmospheric Cherenkov Technique) method. During the 2011-2012 observing season,
VERITAS implemented a new target-of-opportunity (ToO) program to trigger
VERITAS observations on a small sample of the highest energy LAT photons. Each
photon that triggered observation was detected by the LAT within the previous
24-hour period and was not spatially associated with a known VHE emitter. We
present here the results of these ToO observations, a discussion of the method
used, and our future plans.
