The Space Between Us Mystery Cache

Here's the thing about caches. We want them to be fun. Especially puzzle caches. FUN! Nothing is worse than an impossible puzzle. But it needs to satisfy both of us. The cache owner versus the cache finder. A balance. Not too hard. Not too easy. You want to feel smart. But I want you to earn it. That's the space between us. You know the cache is there, just waiting for you. Go forth and find it!
