Back From Trip to Outer Limits

I've just returned from two days in the way far north of California. I had to attend to work at Humboldt State University. I smelled burning marijuana only once in the entire 2-day trip. It was 7:30 in the morning, and I was running around the streets surrounding the downtown plaza. Only once is on the low side of what I had expected. I think things are changing in the the north north of California.
