This text has been encrypted using two key phrases (which is a big hint on the cipher used). I have chosen the titles of two of my other caches for these phrases (naturally using just the alphabetic characters). So you just have to guess which ones I've used.
The cache is a one litre clip top container, large enough for most travel bugs. There is a hint for my Cutmill puzzle cache GC20W4Q on the back page of the log book.
Please don't leave any spoilers in your log and have fun.
