This is further interesting, I went to Fortis's website looking for more info on the VCR Island pipeline and found some additional information on the Woodfibre LNG project including the preps to expand NG service to that point (and not beyond).
They offer a U-Tube video which can illustrate to readers far away the challenges of BC topography, even in Vancouver's backyard. Maybe it brings an appreciation of the heart strings that being pulled upon for TMP expansion, a project I am fully in support of but understand the opposition for those more in tune with nature than the tax base.
