When I was a kid, we were heading out on a fishing trip. Me my buddy and his dad. It must have been around 5 AM; maybe earlier; and I was in the back seat, right in the middle of what seemed like a boat of a car. I had a pretty good view of the entire windshield, or so it seemed. We were driving out through the hill towns side roads and we had just come up over this hill and the lights shone on a Great Horned Owl, full on direct swoop. I had a perfect view of the entire event. Wings looked as wide as the hood. Talons stretched out, snatching up a skunk. My friends father yelled out an expletive and we did a really mild skid, we basically watched this thing swoop down, pick up the skunk and fly off. We were all yelling "Did you see that!?!? That was probably the day that really sparked my interest in wanting to see and learn more. There was always an interest there but that was probably the moment. I know everyone's story is different and love to hear them so if you know of a thread, send me a link.

I sometimes get asked about my set up.
Equipment - I currently use a Nikon D300s with a sigma EM-140 ring flash attached to a fixed 85mm Nikon lens. The Nikon D300s is discontinued and currently goes for just under $200 used. If you've seen my photos, you know what its capable of and I highly recommend it as a good affordable entry level to digital, macro photography. The ring flash I use is also discontinued and even though I've gotten used to the ring flash, I don't think I'd recommend it. Had an issue with the hot shoe and it's durability.

Major project interest - I am currently working on photographically documenting all the native species of slugs county by county throughout New England and bordering New York in an attempt to extend/complete the ranges documented in The Distributions of the Native Land Mollusks of the Eastern United States, Leslie Hubricht 1985. I have spent the last three years searching for and studying these slugs however due to exceptionally dry seasons progress had been slowed way down if not haulted at times but because of an exceptIonally wet season this year things are off and running with excellent success so far. My interest in the native species extends to Canada, the West Coast, Mexico, Central and South America however due to a lack of resources on several levels I felt it best to focus my main attention on documenting what I can within a reasonable distance and the family Philomycidae is my primary target.
