I could say that you didn't really try. If you've only spent 8 hours in 2 years looking for sheds, you aren't trying. I spend 8 hours a weekend looking for em easily. They don't just jump in your pocket, it takes a lot of boot leather, and time to find em.
I have 14 sheds this year, and probably more than 100 hours looking. 3 matched sets that go 120-150.
I realize that in PA you may not find as many, but they are there. Especially since the AR's.
Yes I have deffinatly tried to find sheds. I haven't litearlly kept track of how many hours I have spent looking, but with school, homework, sports, and all the other distractions, I really dont have a lot of extra time on my hands. Plus the area I have permission to hunt is only about 10 acres, so I search every square inch of the property.
