I had this problem year after year in the beginning. I stopped all that, though. Now, I go out and find a patch of briars or thorny bushes, cut a belly crawl path through them, explore a little bit, then cut down an arms length. Crawl a little more, cut down some more. Since this time I haven't had any people problem, and it keeps the deer out. I still have to cage them, but now I don't have to worry about the cages being spotted, just that ground hogs like to pull em down.
