Had a minor collision with a group of pedestrians this morning. Motor traffic was backed up/stopped, so they were crossing against the light without checking to see if anyone was coming in the bike lane. No injuries worse than a couple bruises, angry words were exchanged. Even though this is the street my office is on, I've decided I'll probably change my route to approach it from the back way - at least 50% of the time I ride on this street someone walks out in front of me (it's smack dab in the middle of a university campus). Also had a close call with a cyclist that was riding on the sidewalk just ahead of me and randomly decided to move into the bike lane. Luckily I was watching him warily (had already seen him nearly mow down some pedestrians) and was able to brake in time. He went on to almost hit someone crossing (legally) in a crosswalk.
