Unsavory 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 in the SW corner of Riverfront Park. If the gates to the soccer fields are open, you can drive within 50 feet of the cache. If the gates are closed, park at the coordinates given below and walk .16 miles to the hide (mostly on paved roads). Be sure to read the logging requirements below.
As Sesame Street might say, this cache is brought to you by the letter "U." Your task is to find twenty caches that start with the letter "U." Each of the words must be different and you must include 8 different categories (icons) of caches. You may include only five traditionals on your list, and no locationless caches, foreign words or slang words are allowed. You may include only two abbreviations (such as US, USS, or UCLA). See my examples below. I hope you do your utmost to succeed at this unusual project and don't find this task unfair, uncouth or unfortunate.
