D.  Anti-bird net.  I am hoping my grapes finally do well this year due to the abundant moisture we received in southern Utah this year.  Last years decent crop of grapes were not much bigger than a kernel of corn but there were several decent sized bunches.  If this year is successful I will have to keep the birds away so I can keep the grapes for myself.
