I'm surprised they didn't have a free-form box for people to type well-reasoned, rational thoughts and present excellent ideas they had not thought about .... and won't read. They only give you the two small ones where they want specific replies. Not a general rant forum that people want.
definitely seems like people feel there are a lot of complaints against challenge caches and that too many are unobtainable. there are easy and there are difficult and that's the fun part of them. gives you something to work towards instead of just going and getting a regular traditional every time.
