I was also expecting a puzzle, not another road trip or two or three. I had to do the levels in stages. I don't have a smartphone so I have to prepare in advance. As someone else mentioned I had to plan for caches I might not find in advance. Because of this handicap, I couldn't pick up other caches that might fulfil the requirements for the next level as soon as I had all of the evidence. I'm not happy about all this running around, especially if I end up going back to the same territory I had just been in. Also, what happens to the additional evidence caches I found helping a friend with his search? Do they count toward the 35? I haven't found all the gemstones yet, so I haven't unlocked it to find out the answer to that question.
