Being on a hill that is glacial spillage,in other words rocks. I spend a huge amount of time picking rocks. The worst thing is shale. When shale frost heaves it manages to surface on edge. Besides being toe grabbers. I've face plant more times I care to think about. They are also tire killers. Either they manage to be like axe edges or like arrow heads. Cutting tires. So this is the time of year I spend a lot of time clearing heaved rocks off all my trails. Best time because they are loose and the ground is soft..My back is shot...Though come turkey and deer season I will appreciate all the work done. How many of you clean your trails?
