Treasure Hunt

So I mentioned to a few people last night about a hidden treasure.  This treasures whereabouts is hidden in a series of encrypted documents. 

 

I've encoded a message below that describes what this treasure is and how to find out more about it.  As I discussed last night in my talk, Frequency Analysis is an aid used in cracking classic ciphers.  Below is a message created using a classic cipher.  See if you can crack it.
