If you don't already love Portland than you NEED to take a long weekend and GO. Like now.
So I taught in Portland a couple months ago. It was my second time back this year to teach and my first time going when it was rainy. Seems weird, right? Last time I went in Spring & it was perfection, I hear summer is a must as well. It seemed fitting to be in Portland in the rain though. First thing my assistant and I noticed of course was the green, but was the leaves turning. Being a born and raised desert rat I am not familiar with what REAL seasons look like. Our very depressed but interesting uber drive informed us that , "This is not fall yet." but to us we were in awe of the color.
