Where's the fun in that???
I've been second-guessed before and try to respond with a bit of humor. So sorry if that offended you. My son and I were at an ecological camp in Central Florida. They were using a fine meshed net by the waterfront to see what lived among the reeds by the shore. Cool. All of a sudden, one of the employees yelled "moccasin" and declared this tiny dock off limits. I had to look. She really freaked out when I reached down and snagged one of the baby banded water snakes. They are the most aggressive and bitey snakes I have ever encountered, and this six-inch monster bit me right off. I though she was going to faint. I showed her the smooth head, and explained why it couldn't be a moccasin. She was still freaked. The kids really loved it.
Later, the head of the camp tried to castigate me for picking up the snake, suggesting that I really didn't know if it was 'poisonous' or not. I showed him the bite, and that it did not contain fang marks, and also made sure he understood the difference between venomous and poisonous. I then suggested that they should really learn how to identify all of the snakes, and not assume that every one of them is dangerous. In fact, unless you do something stupid, like pick them up, even if you encounter one, they will leave you alone.
