Hunt Highlights:
· At one point we were afraid we had lost the balloon payload as we did not hear the APRS or beacon for about a hour
· We got lucky after driving near the site of the last transmitted packet and just barley heard the beacon
· We converged on the payload by direction finding the beacon once we could hear it well enough
· Balloon was first found by following the sound of a piezo buzzer installed for that purpose
· The payload was hung up about 35 feet above the ground in a dead, rotten Sweet Gum tree -Tree branches easily snapped off when climbing attempts were made.
· We were unable to retrieve the payload on Saturday evening as dark overtook our efforts
