"Okay, campers, rise and shine, and don't forget your booties 'cause it's cold out there today. It's cold out there every day. What is this, Miami Beach? Not hardly. That's right, woodchuck-chuckers - it's GROUNDHOG DAY!" In honor of a classic (once again), solve the puzzle and find the prize!
At the posted coordinates there is no cache. The road divides here... Does this all sound familiar? Maybe you have seen something like this before on the geo-map... It will be good to know a little history to solve this new puzzle, but there also is no cache at the previous solved puzzle coordinates (it is gone now). This is a new puzzle that you will have to solve to find this new, nano-sized, bison cache container within 2 miles of the posted '?'
In anticipation of an area geocaching event later in February (GC81F8Q), part of this puzzle involves this fun scene from the now-classic 1993 movie Groundhog Day:

Question A matches the answer: "This country's largest lake, Chapala, is located near the city of Guadalajara"
Question B matches the answer: "Seneca is the largest of these lakes in west-central New York"
Question C matches the answer: "This South American lake drains into the smaller Lake Poopo in Bolivia"
Question D matches the answer: "Milky-colored from glacial clay when entering Lake Geneva, this river is clear blue upon exiting"
Now to find this new cache, go find the rest of the puzzle to find out what to do with A, B, C, and D. Have fun, woodchuck-chuckers! Additional Hint: Or fher gb ergevrir Uvccb'f arjrfg zrffntr erpragyl cbfgrq gb gur byqre pnpur cntr...
Once you have solved the new puzzle for the new coordinates, you will find nearby parking close to GZ; the geo-checker provided will give you some suggestions. Please avoid searching on any private property, as that is not necessary. Searching after dark is also not recommended. Please to not do this. A good hint for how the very small bison small latching container is hidden at GZ will be provided by the answer on the geo-checker once you get the correctly solved coordinates.
Happy Groundhog's Day, woodchuck-chuckers!
A geo-checker is provided for you to verify your solution. This is helpful to ensure that you are not looking in the wrong places (especially with private homes in the area). Parking suggestions will also be provided once your solution is correct.
Previously solved coordinates (before 6/29/2020) are now INVALID. Please do not use these. There is actually a private home sitting right on those coordinates. (This was not there when this cache was hidden, nor for the month or so of finds after that date. There was not even evidence at the time of hiding that any such change was to come to GZ.) Please message or email the CO if you have old coordinates and do not want to re-solve the puzzle. Otherwise, please solve the updated puzzle for the correct coordinates. Thank you!
Note: Because the container is a nano bison small, please bring your own writing tool. The log slip is "Rite in the Rain" paper, so it should resist getting wet, however, a pencil will work best if the slip is wet when you go to sign it. If the slip is dry, a standard ball point pen will do fine. Water-based inks may not write on the paper very well and should be avoided if possible.
A big thank you to beat62 for the original container for this cache. The container was received as a gift from him as part of Profbrad's 2018 Bison Exchange (GC7Z5HM). It has since been replaced when the original GZ was overtaken by a house.
A congratulations on FTF goes to Profbrad . Way to "...get up and check that hog out there!"
