Cache is NOT at the posted coordinates.
It was only a matter of time before this old computer of mine went up in smoke. Of course, it's my own fault. I waited until the last minute to work out some new puzzle ideas for the MNGCA Fall Event and, tonight of all nights, I spilled an entire pint of my homebrew beer all over the keyboard. Copaman took it in stride and told me to just do the best I could and get something out there for cachers to work on before they get here. I feel like a class-A space cadet, but here's here's all I managed to get printed out. I hope you can solve it.
