Pinciples of Risk Assessment

Risk = Hazard x Exposure

Outcome might've been different had we factored in "dog crap" as a possible hazard. Exposure is relatively minor but widely spread. (Doesn't take much, does it?) Will probably spend the rest of the weekend trying to get it off the boots, snowpants, sleds, inside of the car, etc. Cripes, why can't people pick up after their damn dogs?!
