TL;DR: This is a cache just like the caches Cowboy Nate has already place along the pathway
Cowboy Nate and I are acquaintances through the Ann Arbor Brewers Guild. I started geocache again during Covid and realized he was a cacher too. We've gotten to know each other better as we share these two hobbies. The cache containers are vials used for home brew yeast. One of Nate's favorite yeasts is English Cider yeast, very appropriate as we start cider season. He had an empty tube and we placed it together. The background pic is just before Nate put the cache in place.
So this is a tribute cache to Nate and our shared hobbies.
