Just time for one today but it was a biggy as this was 365/366 days cached on. How this was a trad I don't know. The cache was easy to find but three mathematical puzzles needed solving to open the box!
Two were easy but the other one was solved by trial and error. A quick sign and then home to write this up. This was also cache 4036 so another milestone. If I get a cache tomorrow it will be 366/366!
