I'd take something with me! But remember he also said, in addition to relieving himself, he was curious to see if what he saw in August was still there. He might have taken it with to poke at the bag (which is exactly what he did with it)
LE took the metal rod based on his statement that he tapped the skull with the rod and it made a hollow sound. LE took it in case that when he did that, he caused some damage to the skull and they could compare that damage with the metal rod. *Note* I'm not saying that Kronk did do any damage but that LE is covering all the bases.
