Trainspotting!
My sweet fixie goes down 17th Ave almost as fast as a Tri-Met test train does – since I don’t have to stop at any of the stations to pick up passengers I can catch up to the train when it’s stopped, then ghost through the crossings immediately past the station while the crossing gates are down.
But if I was in the train I’d be enjoying the air conditioning instead of melting in the heat :-(
