Ok everyone, I couldn't quite find a thread with this, so here goes.
Let's hear your opinions on this: What are the most difficult to access caches in the United States? Not most difficult to find, just difficult to access. It would be great to be able to compile a list of the the "50 Hardest" or something of that nature. If possible, let's try and keep it to "Traditional" caches... not multi caches.
It would be nice to have a feature where you could search caches by difficulty of terrain. Maybe there is, I just haven't found it yet.
Thanks and happy hunting!
