Another Year Older ... 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.
