I remember a very dangerous snowboarding trip to Alaska in Janursry one year. I was so prepared for the cold and the steep mountains.

I ended up knocking a crown loose on a back molar in the hotel, and our whole expedition had to make an unplanned trip back to Juneau to find a dentist.

Injury by toothbrush. Go figure. Thank goodness I was traveling with someone who had a well stocked first aid kit!
