Has anyone ever thought of awarding cache points per find based on terrain and overall difficutly. Then based on the number of points a person has accumulated, they are then entitled to a different level of caches. Kind of like memebers only but in order to see the next level of caches, you would need X number of points.
I.e. 5, 5 -- 25 points. 4,4 -- 20 points, 3,3 -- 15 points, 2,2 -- 10 points, and 1,1, -- 5 points. You could also have spin offs like 5,3 = 15 points, 1,3 would get 10 points, etc.
