Boxcar Challenge Mystery Cache
retiredprof: In light of geocaching's recent changes to the publishing rules, I am archiving all 150 of my challenge caches. I am a retired psychology professor, not a computer programmer. I am simply unable to comply with the new geochecker rules. I am sad that I have to do this. For those who have already begun any of my challenge caches, please note that you can still log archived caches. If you have any problems with this decision, please contact the geocaching authorities so that your suggestions may be considered.

The cache is hidden along 6th street in Marysville at the above-listed coordinates. You can drive right to it. In order to log the cache, you must first find 25 special caches, as explained below.
************LOGGING REQUIREMENTS************
The number 6 is an interesting number. There are 6 geese a laying, 6 strings on a standard guitar, 6 legs on an insect, 6 points for a touchdown, 6 as the shortstop's number, 6 years for a US Senator's term, and 6 sides on the cells of a honeycomb. Your job is to find 25 caches, each with the numeral 6 in the title. The 6 must stand alone...no other numbers or letters with it (altho the pound sign is okay), and no Roman numerals or the word "six."
There is no time limit involved, you may already have found the required caches. When logging this cache, list the requisites caches as shown below. Have fun...and, as the wing man said to the pilot, "don't worry, I've got your six"...
