- I found a good description of lightning propagation and voltages that
might be induced when a tree is struck.
my interpretation is when a tree is struck, flashover to an adjacent
GROUNDED object is a danger. Since the hammock is high resistance to
ground, it probably wouldn't be seen as a potential grounding path.
On the other hand, the tree to which you are tied will probably end
up with discharge damage in a line down the trunk which would
probably vaporize your rope/strap where it is tied around the trunk.
