Attached to a fence? It's not a micro, is it? That leads me towards thinking it might be, but I could be totally wrong.
Many, many people don't like front yard caches, and don't do them. Some who know me might be surprised, I've probably done over a dozen, including I think 4 on one road trip when I had two 11 year olds with me, who weren't too interested in going on hikes in 90 degree heat.
Back to my first little mini-paragraph, every single one of the dozen or so I've found have been easy to find regulars, or even Large's. If I see a micro in someone's yard, immediate plonking on the ignore list. I'm not going to walk back and forth in someone's yard looking like an idiot looking for a micro with a scrap of paper to sign. The only possible exception would be extremely rural, as in the closest house is so far away, they couldn't even see me.
I decided to place one there. It is a micro, but it is something that isn't seen a lot. I promise it isn't just a film container sitting on top of a post.
I placed it in my yard so there would be less of a change that it would become detatched and make it pointless
One person has found it, didn't even know they were there.
