I came across this spider years ago, while looking for salamanders (which is how I found most of the animals shown on this blog). It was on the silt fence, and when I held the camera up close to it, the spider kept running toward it. Reminds me of the way my cat approaches strange dogs — fluffed up and growling, but too curious not to approach and sniff the dog.
The constant motion made it very hard to get a clear photo. When I got around to uploading them from the camera, there were twenty very blurred pictures, and this one.
