Hickory Dickory Dock the mouse ran up the Clock!
Answer these two questions to get the final coordinates:
Question 1: What is the Number on the cache and log sheet for #8 North Drove : Stinger of a Heron Make this A.
Question 2: How many letters in the second word of the container type found at #10: Russia Re-visited? Make this B.
The cache can now be found at: N 51 (A-1)5.88(B-2) W 002 4(B+2).7(B)(B-A). Tweezers helpful.
Maximum stealth is required as the location is popular with dog walkers. Please be careful with the container and place back carefully as found. There is no need to yank/pull. Bring tweezers.
Enjoy and congratulations on completing the North Drove Series!
