Keeping deer out of the orchard...

has been a real challenge this past year.  We have been using an inexpensive solution of 25 lb. fishing line strung at 1 foot intervals between 8 foot stakes.  When the deer strolls into the line, his automatic reaction is to back up.  But not before breaking a line or two.  Last weekend I spent hours restringing the "fence."  Although the barrier has never been completely "breached" it does require regular attention.  Perhaps a real fence is the answer?
