Some would disagree that The Pacific Northwest
is an adequate description for the region
that includes British Columbia
and other parts of Canada
, as BC really is southwestern Canada, not northwestern. Have to be fair to our neighbors to the north
Some people call the greater BC-Oregon-Washington area "Cascadia" to be more inclusive.
Many people also equate the Pacific Northwest with rain, although it is much drier on the east side of the Cascade mountains in Oregon and Washington. Most people don't know about the Oregon high desert.
Many of us (I'm from Oregon) would agree, however that there are plenty of (western) washington-centric pacific northwesterners.
