Notes on the BQE

Have you noticed that lately the BQE running over Park seems to be...leaking? Water is ALWAYS pouring off of it and onto Park, even when it's not raining. Where is this water coming from? Maybe it's best not to know. Also, this free parking under the overpass seems weird to me. Obviously people are parking here, and it seems it's allowed. But it seems like parking there screams, "Steal/damage my car!" Anyone park there? The arrangement seems very intriguing.
