Of course, I was wrong.
While cooling temperatures generally lead to an increase in social and psychiatric complaints and a slight drop in the number of traumas, this weekend bucked the trend. One (surprise!) no-helmet motorcyclist arrived in traumatic cardiac arrest and was already too far gone. A second MCC victim arrived with a nasty forehead hematoma and amnesia. One drug deal gone bad led to three gun shot wounds the chest, while an altercation outside a club resulted in a mere single GSW to the foot.
At least the second motorcyclist had on gloves and a proper winter jacket, if not a helmet. Otherwise he may have caught a cold.
