Bicycle detail

I was riding the MAX and got a phone call just before I got to my stop. I got off and realized I left my bike. I chased the MAX down the street and could not catch. I went to the 6th Ave from the 5th to catch it on the return trip through town. I looked in the next 5 Green line trains for an hour and my bike was gone. I went back to the 5th Ave and rode the train to the end of the line and got off to talk to a Trimet security man. He told me that they don't remove bicycles at the end of the line at PSU. He said that the trains make a 25 minute round in the downtown area, so I knew I was at the right train if someone had not stolen the bike.
