The cache is not at the published coordinates. You'll have to answer a simple riddle to get them. Before we get there, perhaps it's fitting that I shed some background on why I chose this location and the name of the cache.
Once upon a time, ages ago, I worked at the popular burger joint near here. Not the one that exists now as that was once a chicken place. Looks like the burger joint and chicken place from my past were torn down. Ultimately, the burger joint was rebuilt where the chicken place once stood. The chicken place is gone, dust in the wind. Anyway, the burger joint I worked at was closer to GZ. Today, its former location is but a parking lot. This and many other simple examples prove to me that you cannot go back. We probably shouldn't, go back that is. Thankfully, mother nature, or whatever you want to call it, doesn't seem to allow us to make that journey rearward in time.
Perhaps you've tried to visit the past. How did that work out for you? Those inspired, I hope you'll share a brief story in your log.
Anyway, my daugher and I hid this cache as we made our way north from the National Zoo in DC on International Sloth Day. We stopped by here for a quick bite and for dear old dad to reflect on what once was and will never be again. The riddle has absolutely nothing to do with the background story.
