Yes, Unintentionally. Wearing a fleece and wool pants, with a hunting anorak overtop, in a snow/slushtorm in october in swan hills alberta, and putting an emergency blanket around myself,
and hiding my sorry butt under a spruce tree... No I wasn't lost I was stuck looking for some
flipping idiot who was, and we'd taken extraordinary measures after finding out he had a medical
condition. After humping through the likely area in the dark, till we were ready to drop we built a fire and bivyed out using the contents of our daypacks to wait for light and try to find the idiot. (We did, ended ok).

It's not my idea of pleasant. Matter of fact it's pretty darn uncomfortable.
