Borrowed this from a cache idea in Maryland:
The cache is at the given coordinates. Before logging the cache, you must complete the challenge given below.
To successfully complete this challenge, you must find at least one cache for every minute of North 37 degrees latitude. For example, for Minute 00, you would need to have found a cache between N37 00.000 and N37 00.999. For Minute 01, you would need to have found a cache between N37 01.000 and N37 01.999 and so on. Once you have successfully found a cache for every minute, you may find this challenge cache and sign the log. To show that you have completed the challenge, please submit a bookmark list of all the caches. There should be 60 caches listed, 00-59.
1) All cache types are accepted except for Waymarks, Benchmarks, Event, Mega, CITO, and Locationless
2) Previous finds do count, so you may already qualify for this challenge.
3) Archived caches that you have found also count.
4) The caches that can be used are not limited to Virginia. Caches from anywhere in the world can be used as long as they are in the North 37 Latitude.
5) For Unknown and Multi caches that span between two minutes, use the given coordinates.
6) This cache does not qualify for Minute 36.
7) Cachers cannot use their own caches that they placed to qualify.
8) For each cache, please give the GC code, cache name, the minute, and date found.
9) There may be many ways to create your list, and there may be a way easier than I did, but I used GSAK, loaded my finds database, and sorted by Latitude by clicking on the column.
10) If you have any questions, please write a note and I will respond.
Note: There is a Macro for GSAK that checks your finds to see if you qualify - ChallengeMinutes.gsk.
The trails are open from 7am to sunset. The difficulty is for completing this challenge, the terrain is for this specific hide.
