Chopsticks!

That could easily be an exclamation. It's also my non-patented way of dealing with tomato horn worms completely organically and chemical free. Well, ok, I use plastic chopsticks but I don't think that the plastic leaches out enough chemicals to consider it to any degree, otherwise I would also have to stop using the garden hose and city water since I know that the lines going to the house are PVC.
Anyway, I found that the little buggers are not as fond of the tomatoes as they are of one of the pepper plants. He had nearly chewed through the entire plant when I found him this morning. The tomato plant he started on was only slightly chewed before he spotted his goal.
I'm going to have to be more strict when examining the plants in the back now. Once the horn worms come they don't seem to stop that quickly.
