Defeat (?)

I've spent more than two days now attempting to get this piece 20m up into the canopy. Dogged determination. Attempt after attempt. Failure after failure. Riding a cycle of excited hope and disappointment. I'm covered in scratches, cuts, bruises, thorns and tick bites. I declared last night that if this morning's attempt failed I'd call it quits. But now it has I don't know if I can.  Maybe just one more trip to town to see if I can find stronger lines?
