Challenge: Find a cache that has not been found for at least one year.
Only need one to pass the challenge, but the owner is keeping track of who has more, so a list would be beter. Here are the criteria:
list caches where the user has found them, and the previouse "found it" or "publish" log are a calendar year or more earlier.
finds must be on or after 12/19/10
second find on the same cache does not count
only physical caches, so no virtuals, earth caches or webcams
bonus: list the number of days since last found for each qualifying cache
