I don't recommend this Bicycle Film Festival movie, Line of Sight, because I advocate running red lights, riding against traffic, cutting off pedestrians or generally riding into the face of danger.
I do recommend it because it is interesting to see the bike messenger community in action, in a series of races at such major cities as New York and Tokyo. As you might expect, the kind of people who finish first at these events are high-octane Type A personalities (and don't be a check-point volunteer who isn't entirely prepared to answer any question they ask).
And it is educational to hear the filmmaker, Lucas Brunelle, explain how bike messengers use the pieces of the road between vehicles -- what motorists might regard as their buffer zones -- to manouevre in and out of places not even a motorcycle can go.
All the clinical analysis aside, it is also an adrenaline rush, with a pulse-pounding soundtrack. Take your meds first, then settle back to enjoy.
