Portland - Bike Friendly?

I used to think Portland, OR was a very friendly bike town. In terms of both the city infrastructure and the people. I do think the city of Portland does try very hard to be bike friendly, what's taken me by surprise these past few months are the people of Portland. Let me say that for the most part - Portlandites are very friendly to bikes; however, there's been a few really rotten apples.

Take for example yesterday: I was riding downtown heading for the Broadway bridge. There really isn't a "good way" of getting to the Broadway bridge from downtown - that there really aren't many bike lanes heading north/east. So, I'm on a street where there isn't a bike lane and I start to hear things like, "The streets aren't for bikes!" and "Why don't you get in the bike lane!" In fact the guy rode right up next to me and start yelling at me. First of all, why is this guy so interested in what I'm doing. I wasn't riding aggressively, nor did I run any red lights; I was just in the middle lane waiting to cross Burnside. I might also add, there was a fairly large backup ... so it's not like he nor anyone else was really going anywhere fast. Oh and I wasn't even darting through cars - just waiting in line. Anyway he pulled up next to me and started yelling (see above). I started to say something, "I have just as much ..." but his yelling pretty much cut me off. After that, I just thought to myself forget it and ride.

I've had a couple of sour experiences on my bike over the past two months and it really has surprised me. I wonder if it's just me or do other people experience similar events?
