Native - that is exactly what I am finding too. Deer do some crazy things. I am guessing you are correct and that deer did his same thing every year on your farm. Back in 2009 I was hunting a buck that I thought would go in the mid 180's, in 2010 I got on this deer. I had multiple encounters and should have killed him with bow and definitely with a gun. I had him at 5 yards sitting on the ground and my shotgun did not fire. Needless to say I gave up shooting the Remington Copper Solid Slugs and Remington received a nasty letter and a few phone calls from me. The deer I was hunting I believed to be well over 200" typical. I also have pictures that would suggest that I was correct about him being that big.
Back to the theory, in 2011 I never saw this deer again, never a picture again, it was like he vanished. I quit running camera's on that farm because I believed the deer died of old age and his rack was never found. He was the type of deer if he was found dead, people would be talking about him. Now that I have learned this theory about deer that have these odd yearly travel patterns I am guessing this deer was back and active on my dad's farm every year around the same time until he did finally die of old age or was killed after his rack had gone down hill. I sure wish I knew then what I know now.
