      I have a question for the list...

      How long is the distance from your balloon to your payload?  I know everyone will have a different answer but in my mind longer is better.  If your parachute gets caught in a 50' tree and the distance is between the chute and payload is 50' then at worst you loose the chute?  I also think that the payload is more stable the farther away it is from the balloon, on the ascent that is.  I do not have any facts to back this up so I could be way off base but it seems to be true in the scaled down tests that Brenden and I have done.

      Thanks for your input,

      Here's what goes with me on every tracking and recovery:

      1. A 40 foot extended Wonder Pole (http://www.wonderpole.com/wp640_630.html) with two special ends.  One is a hook made from 3/8 inch threaded rod.  The second is an old pruning saw blade.

      2. The EZHang system (http://ezhang.com/index.php?_a=viewCat&catId=1) (a Hyperdog Sling Shot, Zebco 33 reel, one ounce lead shots, and tennis balls, 250 feet of 300 pound test line).

      3. A rope saw (mine is a Sears model that is no longer available, but here is a similar product http://www.treehelp.com/itemdesc.asp?ic=GM-CS-48)

      4. Corona Clipper Razor Tooth Pruning Saw

      5. An assortment of extra ropes (approximately 200 feet) for extending the rope saw and/or pulling on limbs/payload strings with a stronger rope.

      I do have a chain saw and axe that I have brought to recovery sites on the return trip, if chain saw is a viable option.  On a couple of occasions, I have hired a tree climber to recover the flight system.
      In my experience, three hours to get out of a significant tree is not too bad.  My son and I spent seven hours on Saturday (after three hours on the flight day) working on retrieving the remaining radio and parachute from BASE 53.  Still need to make one last return trip (ran out of daylight) to finish the retrieval.

      My latest flight took three hours to remove from trees.  What is everyone carrying for tree removal? 

      Onwards and Upwards,
