I do treasure hunts in any city that I can, I already know about geocache are there others?
geocaching.com is a website that allows people hide or find caches, then paste them into the website so that others seek. I'm enjoying the site, but I am out of the treasures to find in my area. I can not find any other websites that do something similar to this, please help me find some.
In relation to geocaching is "benchmarking." It is similar to geocaching and officially tied to geocaching.
