@Paradox even then, i feel i can't get it quite dark enough.. as well, most every time i've been on anything it's been at home, indoorsfrom what i've felt, less sensory input for one sense means that another can become more prominent... music tends to be lots of fun in that state
i suspect a walk while tripping could be a bit fun, but haven't really tried it.. not worth the potential trouble i think :/
