31 Days Of Geocaching: Coe SP Walkabout Mystery Cache

The cache is NOT at the posted coordinates. 

It is within two miles of the posted coordinates. But these are Coe miles, so travelers beware!  There might just be a little bit of up and down involved.  (Hee, hee, hee.)  Answer the questions below to calculate the final location.

Yeah! It is Geocaching.com’s “31 Days Of Geocaching” celebration!  They are encouraging us to get out and cache, enjoy the outdoors.  I was targeting some other activities the day this cache was setup, but had a last minute change of plans.  What better way for me to celebrate AND to blow away a gray mood than a walkabout in one of my favorite parks?!  A rare cool August day at Coe.  A long summer day allowing hours of caching time.  Miles of paths to follow. A backpack full of containers. Time to hit the trail!  Time to visit new places. Time to visit some I have been to before.  Let’s see, what would be an appropriate number of new caches to drop on such a day?  Let’s start with this one puzzle/mystery cache and see where we go from there, shall we?

Here are the questions. Answer these and find the final treasure.  Searches of the Geocaching.com and the Coe SP related websites will yield you the answers.  Google search and Wikipedia will likely be needed too.
