Like sign language we are left to interpret symbiology and messages that communicate a particular message. Sometimes in life there are quick learners and slow learners; quick thinkers and slow thinkers. When a beast uproots a tree growls while flashing teeth I think, it is telegraphing to me how strong it is and asking need I want a more proof? It is not intended as a smile as in greetings. So, “X’s” are like that international sign language that everyone knows and interprets differently. When the “X’s” are found in the woods they can be construed as a territorial warning like a posted No Trespassing sign. Or, it could interpreted as meet me here at this “X” spot and we’ll discuss this in manner in which you will understand. If the message still isn’t clear, they may visit you when it is advantageous to them – not you, when you least expect it, more likely when your guard is down. If you still insist on ignoring these subtle messages if you post camp in that area, they may drop a tree near your tent for a wake-up call. Pay heed and leave or not.
