The coordinates listed on above will take you to the museum. You will need to enter and look at the pictures on the wall (if it is closed, just peer through the glass doors) and find his image with the food bowl. Using the picture, you will be able to calculate the location of the actual microcache - which is about 0.6 miles away.
The cache is not at the posted coordinates, but can be found at:
