Driving in Cambridge and Somerville is a real challenge. You must constantly be aware of pedestrians with little regard for street crossing etiquette, potholes large enough to swallow small mopeds, and cyclist who think that traffic laws do not apply to them. I consider it a good commute when I only collide with one of the three. Occasionally one encounters bikes that stand out from the rest and although this one was resting at the time, I particularly liked the selective use of yellow paint to enhance curb appeal.
