I'm forever stopping to take pictures of things I spy on the ground. These photos don't usually make it to the blog, with good reason. Frankly the ground isn't always that interesting to other people.
You might have to click on this photo to get the effect of the delicate, silver trails on the sidewalk in the foreground. I know snails make them because I've seen them in action. I don't remember seeing snail trails anywhere else but in southern California.
John and Boz usually move on if I take too long shooting. I could post an entire series of photos of the ground, with my two guys moseying off into the distance.
