I returned home late last night from Portland, OR.
While there, we visited a few of these hobby shops.
Since there was an overwhelming response and interest to my thread

here is the information.
There are about six independently owned in Portland, and one Hobby Town. All of these LHS are within approximately 8 square miles! Tammies Hobbies is in Beaverton, OR which was described to me as the biggest around the Portland area.
If you bridge this fact with the local weather pattern there, then you have quite possibly a plastic model hobby mecca.
These are the shops that my buddy and I visited:
