I have only been geocaching for 2 weeks. I have found 16 caches, and am having trouble finding challenging geocaches. I have done several 4-star difficulty, 4-star terrain geocaches which have not seemed all that difficult for me. Is there any place where geocaches can be rated by the FINDERS rather than the HIDERS? I need more difficult geocaches! Distance from me, time, and cost are no object. Thanks!
