We found two sheds on our 40 acres west of here.  One was a small spike.  Here are a couple of pics of the largest shed.  It was pretty tall.  If it helps, I have one pic of it lined up with my foot.  This particular running shoe is a size 7 women's!  HA HA!  On the close up pic, I think you can get a pretty good feel for how thick this shed was by comparing it to my finger that you can see in the pic as well.

Also found a heck of a rub we missed seeing last fall.  Think that buck must have been trying to rub his way thru the whole dang tree!  HA HA!
