No Signs At All

Mark looked around but noticed there were no footprints around the cabin and in front of the door, so it was impossible to tell if someone had been using it or not. How did the tenant of this structure enter and leave the cabin without leaving any traces at all? Mark had another idea. Whoever built this wanted to remain incognito. The person obviously wanted complete isolation and made sure there was no evidence of their presence left behind. Why would this person go through such trouble to hide their presence?
