Setting up the backyard zip line has occupied my mind for some time. The good thing is that it works perfectly. Here are some notes.

Wow, I need to work on improving my sketching.

Additional Materials:
I didn't have trees in a convenient spot, so set 4x4 steel
posts - 24' 11GA cut in half (for 2 posts).
The posts need a 45 ° tie-back (guy cable) anchored. The anchor I used
is called a deadman.
I used high capacity truck straps, chain, pipe and concrete.
What I like about the design is the 45 ° which will have a footprint of 10 feet
(at least in this application) can be removed when the zip line isn't in use.
If I were doing a more permanent installation, I'd weld or fasten a steel tube
and anchor it.
That's the gas line about 16" down.
