Challenge of the Double Digits Mystery Cache

This cache has been archived.

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.

Geocache Description:

The cache is hidden in eastern Yuba City, you can drive right to it. Be sure to read the important logging requirements below.

************LOGGING REQUIREMENTS************

Numbers between 10 and 99 are important to us. At 13 we become a teenager; at 18 we can vote; at 21 we can have a brew; and at 25 our automobile insurance rate goes down. Your task is to find 25 puzzle caches, each with a different numeral in the title between 10 and 99 inclusive. No duplicates, and no written-out numbers. If a cache title has two double digit numbers, you may only use one of them. And only two caches from a series are allowed. See my examples below.

There is no time limit, you may already have found the required caches. When logging this cache, list your cache finds as shown below. And, remember...these 25 caches MUST ALL BE PUZZLE CACHES. I hope you have 99 hours of caching fun while pursuing this project...
