Still haven't found any sheds this year. However, a few weeks back the pup did lock up and spin 180° to dive under a bushy Pine and found this.
At first, I thought it was a dead deer or something by the color of the frame in the vegetation. Seems its been there at least a season, with the vegetation grown up around it (not piled up on it), and the fabric/straps faded a bit.
Not sure why someone would haul this thing all the way to the middle of 11 acres, to leave it under a nondescript pine among 100's of the same....literally in the middle of where all the deer hide and bed.
