While hunting for one wiley cache, I got stuck hiding in the brush. The cache was just off a walking path behind a bench. Just as I had given up trying to find the container, a walker stopped for a breath on the bench. I was stuck. I could not come barreling out of the bushes so I just squated on the ground and waited. After quite a while, he left and I could come out. The sad part of the story is I didn't find the cache. In fact I was off by about 50 feet in the branches another tree. (I found it the following day.)
