I look for location too, look for the trails/funnels and when you find the spot, look for the tree and if there is not one, dang!

Ispoke to Myles Keller at hunting convention about 10 years ago. He said that he looks for "Killing trees" I said "huh?" He said a killing tree is a tree located at a spot where the contours of the land make the wind thermals raise up making it so your scent is carried away. He said they are very hard to find but he has several of them in his favorite hunting spots and he visits them year after year and they never stop producing. Ipersonally have not found one yet but my buddy and I always half joke about finding one of these mysticaltrees.
