All site search functions seem to work like that concordance in the back of a Bible...not well.

I am reading about the magic 25 to 30 degree angle for hanging my WBBB and also noting some variations depending on the distance between trees. All this is not making a dent in my tiny (non-math comprehending) reptillian brain. Does someone have pics with diagrams to explain this juju? My thought was to set up my hammock until it felt just right and then do a redneck measurement from the gathered end to the tree (assuming the tree is 90 degrees). The 'neck measurement is my arms length (38" reach). Did I mention my tiny (non-math comprehending) reptillian brain?
