The cache this trackable was dropped in was recently archived. The cache owner no longer lives in the area, so I had a hunch the container and this trackable were still out there. Today I was in the area, so I retrieved them so I can get this one moving again.
Too bad I didn't have Ivysaur earlier today! I did quite the bushwacking on my way to finding a couple lonely caches, one of them over 2 years lonely!
