Cache is not at the posted coordinates. Solve the puzzle to locate the cache.

Barcodes are ubiquitous these days. Here's a UPC-A barcode. Can you decode it?


The image “upc.jpg” cannot be displayed, because it contains errors.

For those of you who don't have a barcode reader at home the 95 bit binary representation of this UPC-A code is:

10101100010010011010111101101110110111011000101
010111001010000101100110100010010010001100110101

Once decoded, ignore a leading 0 (if you have it) leaving you 12 digits. Also ignore the last as it's a check digit. Using the remaining 11 digits the cache is at:

39 AB.CDE   10F GH. IJK


You can validate your puzzle solution with certitude.

I'm happy to officially log this one. Thanks to the owner for putting the replacement.

Cache was missing. There's been a lot of change in the area. I've replaced the cache. The coords are off a bit but the location should be obvious from the checker hint.

Write note 01/23/2022 By sleuthers
I'll check on it. It shouldn't be too hard to find (if it's still there) given the hint in the checker.

Didn't find it 01/23/2022 By vegantriathlete
I would say all the same things everybody else said in their logs, except that I don't get to claim a find. It wasn't in the first place I looked or the 2nd or the 3rd or the 4th. There's obviously been work here and things have been moved around a lot. I don't want to have to toss all the rocks to see if I can still find this one.

Glad to complete my sleuther puzzle for the evening. I waited to do this one until I had the patience. It wasn't too hard to solve; I just had to be willing to spend the time.

Thanks for the quick find.

As my caching horizons expand I realized that I have to be well rounded. That means picking up mystery, multi, whereigo, and earthcaches. The first two I don't mind so much. But solving mystery caches requires a bit of effort on my half. So I've been working on them. Today my journey took me to Highlands Ranch and Broomfield. Found all the caches I was looking for.
For fun I solved the puzzle both ways to test my barcode reader app. Worked well enough :)
Happy Fourth of July!!

Out and about with FeartheFish to work off some of the puzzles that I had solved up in the NW part of the metro. Decided to let FtF risk his life and run across traffic! Nice puzzle and easy find. TFTC!

Needed our puzzle for the day. Tried to find one in Parker but failed miserably. So we made the 40 plus mile trip to get this one at 9PM. Oh no, not rocks, especially at night !!! Searched a bit, read some logs and realized we had forgotten about the helpful hint that came with the checker. Grabbed the cache, signed the log, returned it to its hiding place and home we go !

The 3 Chihuahuas, 2 Lab Lovers, Nerak2001, and I stayed with Dusty River after the CITO got snowed out to solve some nearby puzzles. We didn't have to stay too long at GZ, which is always a blessing with this kind of hide. TFTC! All is well with this cache. Happy caching!

Lucked out and went right to it. Signed log. Thanks for the puzzle and the cache!

We almost gave up because we thought we had look under most of the rocks that were not cemented in place. Gave it one more try and low and behold there it was. TFTC

Found it 11/07/2017 By Alpenist
TFTC Normally I hate rock pile searches but this one was specific enough that I was able to find it, even on a dark and snowy night. Thanks for the cache and liberal hint,

Caching around town with BroncoCole picking up some mysteries/puzzles. I don't know this area well so I'm glad BroncoCole was the one who was driving. My job was to help entertain his kiddos. What a cool puzzle. This is a first for me.

Found Code BLACK and WHITE on February 19, 2017 using Cachly for iOS.

Thank you, sleuthers for placing a fun cache for all of us to enjoy. I look forward to finding more of your caches.

The area has changed a bit but I could replace the cache roughly where it was. Checker hint has been updated.
