Departure Question

Thanks to all for previous helpful replies.
Here's a departure question. (Those who do not fly real airplanes under
IFR need not feel compelled to reply):

I'm departing a non-towered field IFR, let's stay East Coast, and say
Bennington (KDDH), departing eastbound. There is a published departure
proceedure, for obstacle (read mountain) clearance. Under Part 91, I am
not required to follow this proceedure, but due to mountain obscuration I
may wish to do so. What do I put in my flight plan, or in my
communication via the local GCO to indicate whether I intend to return to
the Cambridge VORTAC or not? Albany approach may have other IFR traffic
coming into Bennington, so they will want to know if I am backtracking to
CAM or not.

Thanks in advance . . .
