On big power trails, we're often in a rush moving from cache to cache as quickly as possible. For this one, you might need a little more time, as there's lots of trees to search.
THE CACHE IS NOT AT THE LISTED CO-ORDINATES.
To find the cache, solve the following questions:
1) Big Ben in London, is not actually a clock; it's a bell. What is it's weight? 13,ABCkg - (hint: it's heavier than 13,500)
2) The Rathaus-Glockenspiel clock in Munich has how many bells? DE.
The cache is located at N35 51.(ABC-262) E128 39.7(DE+36).
It's at head hide, although if you find a nail sticking out of the tree without a geocache attached, please report it as missing.
