RE: sheds
Look in the trees! LOL Seriously, look on the south side of hills & draws, in bedding areas, travel corrodors, etc.
I did however, find a shed in a tree once! It was wedged about 1.5ft off the ground in two cedar saplings that were growing right next to each other. I took a pic of it, b/c I'm sure I'll never find one in a tree again!
