I got really frustrated at one point, and wrote some code to display all the possible coordinates sets. I plotted them and was planning a brute force attack if this puzzle continued to stupify me. Then after a lot of staring at it, it suddenly came to me.
I checked the typical location first, then saw something else that looked strange. That was it. Whew.
