Some evenings Steve and I venture over to a local park to skate, well he skates, I usually stumble, take forever and contemplate the least painful way to stop myself when accelerating down a hill. Anyway the last time we went I took a few of my cameras and snapped a few pictures at sunset right as the fireflies came out. At one point I could see a deer off in the distance, once I got home and uploaded my pictures I was pretty pleased with the outcome- it actually turns out it was a buck! You can see the full sized images on my flickr page. Here are my favorites.
All of those little yellow specs are fireflies! I kept making noises so the deer would continue to look at me and not move, my plan worked perfectly.
