To work out the coordinates of this cache one must look out for clues at the Millennium Loop caches. Clues are of the form X=N, where X is a letter and N is a number. There are seven clues - A thru G.
The coordinates are: N 52 AB.CDA, W 8 E.FCG
The sum of the nine digits just calculated should be 32. The cache is within Glengarra woods, and not very far from water. It is a tupperware container.
