November Challenge Mystery Cache

Complete Title: Minnesota Blackout by November Placed Date Challenge.

1. What counts and what doesn't? Caches that have physical logs, i.e. traditionals, multi's, puzzles, and letterbox hybrids but not virtuals, events, earthcaches, webcams, or locationless caches.
2. Why just Minnesota? Because you should be proud of the state you cache in.
3. How about using find dates rather than placed dates? Wow! That'd be 1200 new caches.
4. Do prior finds count? Yes, but that's not as big of an advantage as it might seem.
5. Why's that? If you just were to find November-placed caches at random, after a while you would start to duplicate placement dates. For example, after about 30 finds of November-placed caches you still would have about eleven to go, after 60 that would be down to about four; only after 120 would you have half a chance of finding them all. And multiply those numbers by about 20 to account for all months and you'd need a couple thousand or so Minnesota finds to have even half a chance. So most cachers should have at least a few caches to find.
6. What are the logging requirements? In either order, you have to find and sign the log at the posted coordinates and you have to either bookmark or email a list of the GCXXX for your 30 finds, each of which must have been found and logged by you personally. After you've done both you may claim the find. Please try to order yours by November placement date.
7. How can I easily obtain the placements dates of caches I've found? One way is to scan the "All Cache Finds" list for your profile.
8. How do I find caches according to their placement date?One way is to scan through caches listed for Minnesota. These are arranged by placement date. You might need to go back through the years.
9. What if I've more questions? Just ask. Anything significant that's been overlooked will be listed and dated here.
