[CTSARA] Wire Antenna - Attach Pulley to Tree?

[jon at thesolomonhouse.com]

HI Everyone! 

I've got some tree folks coming to my house this week, and felt it was a
great time to have them put a couple of pulleys on some trees so I can
FINALLY hang my 40m dipole and get back on the air.  Does anyone have
suggestions on how to do this?  I'm half thing some straps from REI and
caribeaners, but wondering what others have done? 

Thanks!
