I have done the cross-Canada drive many, many times. I usually drive to Winnipeg in one go (24hrs), then Calgary or as far as Golden the next day, making the coast the following day. Once, I was driving through Rogers Pass late at night. You know how sometimes your subconscious picks up things you don't notice consciously, like animal movement in the ditches? My subconscious saw one of the black/yellow striped avalanche control road barricades, tipped up (road open) and screamed at me "Look out for that giraffe!!". I pulled over and had a nap.
