I don't know how I have missed these caches along my route home but here is a 4.5 difficulty in my hand. The challenge was no description nor hint and a healthy distance from GZ.
Basically it was the cache and your skills. I started with my dog chasing my tail technique then ended up just looking. At this point you relax and think geocache.. Oooohm.mmm.
I suddenly went way out of the zone looked down and knew I had it before moving the cover. There is few things that give such satisfying thrills as when you make a connection like that.
