Did some laps today and on the descent at the north end of the loop, just before Lasker Rink, a few kids were pelting cars with those large green fruits (don't know the name, but they're about the size of a billiard ball). Fortunately, a cab and a minivan were between me and the kids, and took the hits (the one time I appreciated having cars in the park!). I stopped and pulled out my cellphone, but the kids bolted.
Keep an eye out - the kids may get weary of hitting targets as large as cars and may opt for the more challenging-to-hit cyclist. The real risk is not the bruise those fruits will leave, but that it might cause you to crash, potentially in front of a car (ok, I'm back to hating the fact that cars are allowed in the park).
