Most of the Challenge Caches are more complicated and not within range of many who aren't real active, so I'm placing this because it's one I would qualify for. To qualify, you need to have found at least 4 cache types of the 15 types listed on Geocaching.com site. Adventure Labs are excluded. There is no time limit. If you're just beginning, you can sign with a "write note" log, but not a "found it".... until you reach the required 4 cache types. Hopefully this will encourage some newbies to get more active.
