  We performed a wide-area (2000 deg$^{2}$) g and I band experiment as part of
a two month extension to the Intermediate Palomar Transient Factory. We
discovered 36 extragalactic transients including iPTF17lf, a highly reddened
local SN Ia, iPTF17bkj, a new member of the rare class of transitional Ibn/IIn
supernovae, and iPTF17be, a candidate luminous blue variable outburst. We do
not detect any luminous red novae and place an upper limit on their rate. We
show that adding a slow-cadence I band component to upcoming surveys such as
the Zwicky Transient Facility will improve the photometric selection of cool
and dusty transients.
