OK - help me to decipher this. On the USC campus, it obviously references USC students - that kind of flattened Mohawk is, in fact, a Trojan helmet. But what's happening with these two particular members of the Trojan Family? Is it a warning that if you're a pedestrian, you might get mown down by a bicycle (a potential hazard just about anywhere on campus)? Or, vice versa - if you're charging along on your bike, that you could hit a pedestrian? Or does it tell us all that, frankly, it's a free for all on this bit of parkway? At least the University's Cardinal and Gold colors have been accurately deployed ... but to what end?
