Thinking of hiding a cache in a spring on BLM land in Cochise County, Az. Has anyone gotten a permit, or whatever is necessary, from BLM for this sort of thing?? Do you know the chances of this going forward? Does this cause degradation to the environment, or some such thing, that BLM wouldn't want. The container is just a water bottle (waterproofness is another issue, but one that I will handle myself). I originally posted this in the General Geocaching Discussions section, but maybe this is a better place for it. Please tell me your thoughts.
