So, for halloween 2013 I wore an arctic ghillie suit and went as a yeti. The various identifications I received from passers-by while wearing a white  full-body dust mop were as follows:
* Mostly yeti.
* A few Bigfoot or Sasquatch.
* One albino sasquatch.
* A few Abominable Snowman.
* Several more than a few Abdominal Snowman, which makes me weep for our educational system especially given that most of those were adults.
* One alpaca. Yes, alpaca.
 Yes, I wore white. I didn't think anyone would get the point if I was an all-black yeti.
