Go ahead and observe and photograph the wildlife (that is still legal), but "hunting" with the intent to capture (even if just momentarily for a photo) is illegal (although I'd love to challenge that in court). Unfair and ill-advised as it may be, this law is the law.
If you are stopped, explain (truthfully) that you are looking for snakes and other nocturnal wildlife to observe and/or photograph (or just plead the fifth entirely). Hooks or bags in your vehicle can be honestly explained if you also plan to hunt on private land. Hooks or bags on your person will be strong evidence of intent. I'd avoid carrying them around without a good explanation.
Lying about hunting bugs, rocks, or nocturnal flowers might get you off the hook. However, LE will know you are lying and they will resent it. Besides, there is no need to lie. Unless you have a snake, bag, or hook in your hand, there is no compelling evidence that you are hunting.
You MAY get cited by an over eager warden despite an absence of compelling evidence. However, any such citation will provide us with the perfect test case to challenge this law.


! But even if it were extremely onerous, I'd forbear for now....
