On New Year's Eve, I found caches in Manassas and Manassas Park, where were Counties (county equivalents) 53 and 54. That also earned me the "Last Cache of 2017" souvenir (Souvenir 39).
So of course, 2018 opened up the next day with the "First Cache of 2018" souvenir (Souvenir 40).
Back in Virginia, I found 3 more, including a challenge cache that was my first difficulty/terrain combo 4/5 (Combo 30) and one from December 2013 (Month 158). It required finding caches in 10 countries, not including Puerto Rico. My December trip to Hong Kong let me claim this one.
February saw another trip to California, with only two caches found. The first was a 5/2 D/T challenge (Combo 31) from March 2014 (Month 159). That completes the year 2014 for me, joining 2002 and 2016. Here the challenge was to find caches at all distances from home listed on the web site (e.g., one less than a mile from home, one 1-10 miles from home, etc.) The cache owner sent me a message expressing surprise that I had met the challenge with so few total caches.
I then found a virtual at Mount Vernon from October 2001 (Month 161). It was the eight-oldest cache I have found.
After that, the next cache I found was right near work. I was getting in my car to go home when I got the alert, so I knew I would get the First-to-Find (FTF). Unfortunately, there was a little drama there, since I accidentally signed the bottom of the log, and others did not notice and claimed FTF after signing the top of the log. Fortunately, it was all straightened out, and I had FTF #14. That also gave me February 2018 (Month 162).
I found another one in Maryland from November 2017 (Month 163) and one in Virginia (no milestones achieved) before heading out on my most epic day of caching yet.
Here are some pictures from logs on that day's caches.
On the drive back, I found caches in Bristol (County 65), Washington County (turned out to be my second one, but I did not know it yet), and Pulaski County (County 66). Now at 21 Virginia counties!
Back in Maryland, I found two more, including one I was second-to-find on in March 2018 (Month 168).
