This tree is located 5 ft. northeast of a large maple stump.
This tree is doing a little better than it's sister (we have two Haralsons).  It had a dozen apples on it - only one has fallen off and that was a couple of weeks ago.
I'm not sure when I wrote the above, perhaps July 2011.  A few more apples fell off in August.  I set them aside to ripen... when I cut them open, the core was black and spreading into the fruit.  Picked the rest of the apples in early Oct0ber - no black centers.  They did have quite a few worm trails within them - no worms - and the clean pieces left were delicious and plenty enough to make a chunky apple pie.
