I went out shed hunting 2 weeks ago. Didnt find anything at all. I am going to be on my spring break next week so will have alot of time to look. My question is how can you find this things. They are brownish with the leaves and weeds everything looks brownish. I looked in area where I knew there was rubs, along corn fields. Didnt find anything maybe they havent dropped them in my area. How can you find them is there some trick?
