Once I got on the MAX Yellow Line, I sat in the sunny light rail car enjoying the view. In this photo the train is on the Steel Bridge just about to cross over the Willamette River. The two sets of tracks you see are for the MAX Red Line and the MAX Blue Line. The MAX Green Line approaches the bridge on the same tracks as the MAX Yellow Line. All four cross the river on the Steel Bridge, then branch out to serve various places in the greater metropolitan area on both the east and west sides of the river. It wasn't until I uploaded the photos to iPhone that I noticed a bit of jet trail in the photo. For more serendipity, there's the Big Pink on the skyline.
I like the blue sky reflected in the Willamette River. And look at all the jet trails!
