Rabbits defeated? Pvc pipe and garden netting.

I think rabbits have been eating my Radicchio.I have cut off some 1/2 inch PVC pipe about twelve inches long. I drive these stakes in the ground, and then take five foot sections of 3/8 PVC pipe, which I insert in the stakes. It makes a nice hoop support.Then I covered it with garden mesh netting. this should keep the cabbage butterfly's out and the rabbits at bay. It seems the rabbits and ground hogs especially like the following: Radicchio, Red Beets, Romaine lettuce, and Brussels Sprouts. I think I planted 12 Brussels sprouts and one has survived. I think I know how to fend them off next year.
