So, I traversed my way down the trail, with my GPS going haywire.
"400 feet this way. No wait, 347 feet back the way I came. Now it's saying 600 feet across the river!"
There wasn't much I could do about the GPS. Some days are just like that. But I still had my hint, "You'll know ground zero when you get there."
Ok, so that should be pretty simple.
I kept on meandering down the trail when I looked off in the distance and saw this.
If you look reeeeeeelly carefully, you can see a tunnel close to the center of the picture.
I'm thinking to myself that this is the most incredible find ever. I get closer, and this is what I see.
I peered into the thing, waiting for a bat/hobo to hop on out, but didn't see anything. It was incredibly dark in there, so I pulled out my flashlight and climbed on in.
Down and down the tunnel I went. It was a tight squeeze, being only about 3 feet tall and 2 feet wide. It was LONG too. It took me a while until I made it to the other side, but I eventually got there.
Turns out this is a rather long drainage ditch tunnel underneath a major walking trail. I hadn't seen anything even resembling a cache inside, and came to the realization that it must not be here anymore.The hobo must've taken it.
Somehow, I turned myself around and began the shuffle back towards civilization.
Notified the cache owner once I was back in front of my laptop, only to get an email back in reply telling me that the cache was indeed on the other side of the river hidden inside of a hollow log, and that they really had no idea what my cryptic log was talking about, with long tunnels and all that.
And so, I went through an old forgotten tunnel for nothing.
