i usually just bring along things like a set of horns to bang together, a tube that i play music through(grunt), i also have this instrument that is fun to play.... it is a little can you turn over and it makes a cool whining sound. i am quite the artist but usually get interrupted with incoming whitetails. i know this is very dry humor, but i usually just bring a little log book and write things down about the hunt and the spot. sometimes i will bring a book when i get bored and read on how to hunt.
