I've managed to place ropes in two tall trees (~75') about 150 feet 
apart.  I want to string a half square on pulleys between these 
trees, with a horizontal wire between the trees and then a vertical 
wire dropping at either end.  The lot is very heavily wooded, so the 
area between the trees is filled with other trees that are 10'-40' 
tall. 

My problem is this - how do I get the vertical wires out across the 
middle and drop them.  There is absolutely no access from the between 
the trees -- it is so heavily wooded that I can't even see the sun. 
The only access is a clearing at the base of one tree (it took a 
slingshot made of surgical tubing and 2x4's to get the ropes up, but 
that's another story).  Cutting the trees is not an option.

Currently, the situation looks like this (the X's are trees, the 
other lines are ropes).

                -                      ---------
               /X\                    /        X\
              / X |           --------         X \
             /  X |          /                 X  \
            /   X |      ----          X       X  |
           /    X |     /  X           X     X X  |
          /    XX |     |  X     X     X     X X  |
          |    XX |     |  X  X  XX  X X     X X  |
          | X XXX |     | XX  X  XX XX X  X  X X  |
          |XX XXX |     | XXXXX XXX XXXXX X XXXX  |
          |XXXXXX |     |XXXXXXXXXXXXXXXXXXXXXXX  |

                ^                              ^
           tree1^                         tree2^


And I want to end up with this (I'm omitting most of the trees here). 
(Again, the X's are trees and the lines are ropes.  Also, the O's are 
pulleys and the h's are half-sqare wires.)

                /===O/--hhhhhhhhhhhhhh----\O===\
               /X   /   h            h     \   X\
              / X   |   h            h     |   X \
             /  X   |   h            h     |   X  \
            /   X   |   h            h     |   X  |
           /    X   |   h            h     |   X  |
           |    X   |   h            h     |   X  |
           |    X   |   h            h     |   X  |
           |    X   |   h            h     |   X  |
           |    X   |   h            h     |   X  |
           |    X   |   h            h     |   X  |

Any ideas on how I can carry the vertical wires into position over 
the lower trees and then get them dropped down vertically?
