I would prefer to see us be able to rate the difficulty and terrain when we post. That way, if you rate your cache a 1/1 and people think it was much harder than that the folks who have not found it could give their opinion. So you would wind up with a 1/1 as the "main" rating but might wind up with a 3/1 if it was found to be harder than the placer thought. I know I placed a tiny cache that I thought was very easy to find but out of 14 logs, only 9 finds and 5 no founds. I rated it a 1/1 because it's basically a walk up cache in a very easy spot less than half a mile round trip.
Just my thought..
