I think you answeredyour original post in the above statement. You hunted 46 times and only went to the same tree twice. Thats 44 different sights.I'll assume you had at least two directions you could shoot at each sight and probably three or four at some others. That's a whole lot of trees, bushes, clumps of grass, dead logs, etc. to remember the distance to. I know I couldn't remember all of those at the beginning of next year, if you can my hats off to you.
