I was out geocaching with a friend last night, when we both mentioned how it's felt like there haven't been very many geocaches published lately in our city of 1.2 million+ compared to last year or the year before. That led me to do some searching. Here is a list of the number of geocaches published per year in my city over the last 10 years:
2008 - 585
2009 - 622
2010 - 659
2011 - 608
2012 - 671
2013 - 537
2014 - 602
2015 - 867
2016 - 581 2017 - 257 (up to Nov. 10, 2017)
